Which statement is NEVER true?
- A.
Square ABCD is a rhombus
- B.
Parallelogram PQRS is a square
- C.
Trapezoid GHJK is a parallelogram
- D.
Square WXYZ is a parallelogram
Correct Answer
C. Trapezoid GHJK is a parallelogramExplanation
The statement "Trapezoid GHJK is a parallelogram" is never true because a trapezoid is a quadrilateral with only one pair of parallel sides, whereas a parallelogram has two pairs of parallel sides. Therefore, a trapezoid cannot be a parallelogram.Rate this question:

Which statement is true for some, but not all, rectangles?
- A.
Opposite sides are parallel
- B.
It is a parallelogram
- C.
Adjacent sides are perpendicular
- D.
All sides are congruent
Correct Answer
D. All sides are congruentExplanation
The statement "All sides are congruent" is true for some rectangles, but not all. While all sides of a square are congruent, not all rectangles have congruent sides. Rectangles can have two pairs of congruent sides, but they can also have two pairs of sides with different lengths. Therefore, the statement is not true for all rectangles.Rate this question:

A parallelogram has four congruent sides. Which name best describes the figure?
- A.
Trapezoid
- B.
Parallelogram
- C.
Rhombus
- D.
Square
Correct Answer
C. RhombusExplanation
A parallelogram with four congruent sides is called a rhombus. In a rhombus, all four sides have equal lengths, making it a special type of parallelogram. Unlike a square, which also has four congruent sides, a rhombus does not necessarily have right angles. Therefore, the best name to describe a parallelogram with four congruent sides is a rhombus.Rate this question:

Which name best describes a parallelogram with four congruent figures?
- A.
Kite
- B.
Rhombus
- C.
Rectangle
- D.
Square
Correct Answer
C. RectangleExplanation
A rectangle is the best name to describe a parallelogram with four congruent figures because a rectangle has four right angles, opposite sides that are parallel and congruent, and opposite sides that are also congruent. A rhombus has opposite sides that are congruent, but its angles are not necessarily right angles. A square has all the characteristics of a rectangle, but it also has four congruent sides. A kite does not have congruent sides or right angles. Therefore, a rectangle is the most appropriate name for a parallelogram with four congruent figures.Rate this question:

In Parallelogram PNWS, what is angle measure W?
- A.
128
- B.
90
- C.
52
- D.
26
Correct Answer
C. 52Explanation
In a parallelogram, opposite angles are congruent. Therefore, angle measure W must be equal to the opposite angle, which is 52 degrees.Rate this question:

In Parallelogram PNWS, what is measure angle S?
- A.
128
- B.
90
- C.
52
- D.
26
Correct Answer
A. 128Explanation
In a parallelogram, opposite angles are congruent. Therefore, angle S is equal to angle W. Since the sum of the measures of angles in a parallelogram is 360 degrees, angle W + angle S = 360 degrees. Thus, angle S must be 180 degrees - angle W. If angle W is 52 degrees, then angle S would be 180 degrees - 52 degrees = 128 degrees.Rate this question:

The diagonals of a quadrilateral are perpendicular bisectors of each other. What name best describes the quadrilateral?
- A.
Rectangle
- B.
Parallelogram
- C.
Quadrilateral
- D.
Rhombus
Correct Answer
D. RhombusExplanation
A rhombus is a quadrilateral with all sides of equal length. The diagonals of a rhombus are perpendicular bisectors of each other, meaning they intersect at a right angle and divide each other into two equal parts. This property is unique to a rhombus and not found in other quadrilaterals such as a rectangle, parallelogram, or general quadrilateral. Therefore, the best name that describes the given quadrilateral is a rhombus.Rate this question:

The diagonals of a quadrilateral bisect both pairs of opposite angles. What name best describes the quadrilateral?
- A.
Parallelogram
- B.
Quadrilateral
- C.
Rectangle
- D.
Rhombus
Correct Answer
D. RhombusExplanation
A rhombus is a quadrilateral in which the diagonals bisect both pairs of opposite angles. This means that the diagonals of a rhombus divide each angle into two equal parts. Therefore, the given information perfectly describes a rhombus. A parallelogram is a quadrilateral with opposite sides that are parallel, but it does not necessarily have diagonals that bisect the opposite angles. A rectangle is a quadrilateral with four right angles, but its diagonals do not necessarily bisect the opposite angles. A quadrilateral is a general term for any four-sided polygon, so it does not provide specific information about the bisecting diagonals.Rate this question:

Which statement is true for every trapezoid?
- A.
Exactly two sides are congruent
- B.
Exactly two sides are parallel
- C.
Opposite angles are supplementary
- D.
The diagonals bisect each other
Correct Answer
B. Exactly two sides are parallelExplanation
Every trapezoid has exactly two sides that are parallel. This is a defining characteristic of a trapezoid. In a trapezoid, the two parallel sides are called the bases, while the non-parallel sides are called the legs. The parallel sides can be of any length, but they must be parallel to each other. Therefore, this statement holds true for every trapezoid.Rate this question:

Which statement is true for every kite?
- A.
Opposite sides are congruent
- B.
At least two sides are parallel
- C.
Opposite angles are supplementary
- D.
The diagonals are perpendicular
Correct Answer
D. The diagonals are perpendicularExplanation
Every kite has diagonals that are perpendicular to each other. This means that the two diagonals intersect at a right angle. This property is true for all kites, regardless of their size or shape.Rate this question:

Two consecutive angles of a trapezoid are right angles. Three of the following statements about the trapezoid could be true. Which statement cannot be true?
- A.
The two right angles are base angles
- B.
The diagonals are not congruent
- C.
Two of the sides are congruent
- D.
No two sides are congruent
Correct Answer
D. No two sides are congruentExplanation
If no two sides of a trapezoid are congruent, it means that all four sides have different lengths. However, in a trapezoid, the two non-parallel sides are usually congruent. Therefore, if no two sides are congruent, it contradicts the definition of a trapezoid. Hence, the statement "No two sides are congruent" cannot be true.Rate this question:

Quadrilateral EFGH is a kite. What is the value of x?
- A.
15
- B.
70
- C.
85
- D.
160
Correct Answer
C. 85Explanation
Since EFGH is a kite, it has two pairs of congruent sides. Therefore, the angles opposite these sides are also congruent. Since angle E is 85 degrees, angle G must also be 85 degrees. Thus, the value of x is 85.Rate this question:

The vertices of a rhombus are located at (a, 0), (0, b), (-a, 0), (0, -b), where a, b > 0. What is the midpoint of the side that is in Quadrant II?
- A.
(a/2, b/2)
- B.
(-a/2, b/2)
- C.
(-a/2, -b/2)
- D.
(a/2, -b/2)
Correct Answer
B. (-a/2, b/2)Explanation
The midpoint of a line segment is the average of the coordinates of its endpoints. In this case, the side of the rhombus in Quadrant II is formed by the points (0, b) and (-a, 0). To find the midpoint, we take the average of the x-coordinates and the average of the y-coordinates. The average of 0 and -a is -a/2, and the average of b and 0 is b/2. Therefore, the midpoint of the side in Quadrant II is (-a/2, b/2).Rate this question:

The vertices of a kite are located at (0, a), (b, 0), (0, -c), and (-b,0), where a, b, c, d > 0. What is the slope of the side in Quadrant IV?
- A.
C/b
- B.
B/c
- C.
-b/c
- D.
-c/b
Correct Answer
A. C/bExplanation
The slope of a line can be determined by calculating the change in y-coordinates divided by the change in x-coordinates. In this case, the side of the kite in Quadrant IV is the line connecting the points (0, -c) and (-b, 0). The change in y-coordinates is -c - 0 = -c, and the change in x-coordinates is -b - 0 = -b. Therefore, the slope of this side is -c/b.Rate this question:

The vertices of a square are located at (a, 0), (a, a), (0, a), (0, 0). What is the length of a diagonal?
- A.
A
- B.
2a
- C.
A√2
- D.
2√a \x00
Correct Answer
C. A√2Explanation
The length of a diagonal of a square can be found using the Pythagorean theorem. In this case, the length of one side of the square is 'a'. The diagonal forms a right triangle with the side of the square as one of its legs. The other leg is also 'a' since the square is formed by equal sides. Therefore, the length of the diagonal can be found by using the Pythagorean theorem: d^2 = a^2 + a^2 = 2a^2. Taking the square root of both sides gives us d = a√2.Rate this question:
