In the diagram, Line L1 is parallel to Line L2. What is the measure of angle 3?
-
110 degrees
-
70 degrees
-
180 degrees
-
20 degrees
Correct Answer
A. 110 degreesExplanation
In the diagram, Line L1 is parallel to Line L2, which means that angle 3 is an alternate interior angle with angle 1. Alternate interior angles are congruent when the lines are parallel. Since angle 1 measures 110 degrees, angle 3 also measures 110 degrees.Rate this question:

In the diagram, Line L1 is parallel to Line L2. What is the measure of angle 1?
-
110 degrees
-
70 degrees
-
180 degrees
-
20 degrees
Correct Answer
A. 110 degreesExplanation
Since Line L1 is parallel to Line L2, angle 1 is a corresponding angle to the angle formed by the intersection of Line L1 and Line L2. Corresponding angles are congruent when two parallel lines are intersected by a transversal. Therefore, the measure of angle 1 is 110 degrees.Rate this question:

What is an acute angle?
-
An angle that is more than 90 degrees
-
An angle that is equal to 90 degrees
-
An angle that is less than 90 degrees
-
None of these
Correct Answer
A. An angle that is less than 90 degreesExplanation
An acute angle is defined as an angle that measures less than 90 degrees. This means that the angle is smaller than a right angle, which measures exactly 90 degrees. Therefore, the correct answer is "An angle that is less than 90 degrees."Rate this question:

What is an obtuse angle?
-
An angle that is more than 90 degrees
-
An angle that is equal to 90 degrees
-
An angle that is less than 90 degrees
-
None of these
Correct Answer
A. An angle that is more than 90 degreesExplanation
An obtuse angle is defined as an angle that is greater than 90 degrees. In other words, it is an angle that is wider or "more open" than a right angle, which measures exactly 90 degrees. An obtuse angle can range from slightly greater than 90 degrees to almost 180 degrees, but it cannot be equal to or less than 90 degrees. Therefore, the correct answer is "An angle that is more than 90 degrees."Rate this question:

What is another name for a 90 degree angle?
-
An obtuse angle
-
An acute angle
-
A straight angle
-
A right angle
Correct Answer
A. A right angleExplanation
A right angle is another name for a 90 degree angle. In geometry, a right angle is formed when two lines or line segments intersect at a 90 degree angle, creating a square corner. It is called a right angle because it is the "correct" or "right" angle in terms of its measure.Rate this question:

What is the measure of the angle labeled x?
-
65 degrees
-
90 degrees
-
180 degrees
-
75 degrees
Correct Answer
A. 75 degreesExplanation
The measure of the angle labeled x is 75 degrees. This can be determined by observing that the angle is not a right angle (90 degrees) or a straight angle (180 degrees). It is also not stated that the angle is supplementary to any other angle, so it cannot be determined to be 180 degrees. Therefore, the only remaining option is 75 degrees.Rate this question:

Polygon A is a square. Polygon B has four more sides than Polygon A. What type of polygon is Polygon B?
-
Octagon
-
Hexagon
-
Decagon
-
Pentagon
Correct Answer
A. OctagonExplanation
Polygon A is a square, which means it has four sides. The question states that Polygon B has four more sides than Polygon A. Since Polygon A has four sides, Polygon B must have four more sides than that, making it an octagon.Rate this question:

If a and b are parallel lines and angle 4 = 45 degrees, what is the measure of angle 7?
-
135 degrees
-
45 degrees
-
180 degrees
-
90 degrees
Correct Answer
A. 135 degreesExplanation
Since a and b are parallel lines, angle 4 and angle 7 are corresponding angles. Corresponding angles are congruent when the lines are parallel. Therefore, if angle 4 is 45 degrees, angle 7 must also be 45 degrees.Rate this question:

A ______________________ polygon is a polygon in which all sides are the same length and all angles are the same measure.
Correct Answer
regularExplanation
A regular polygon is a polygon in which all sides are the same length and all angles are the same measure. This means that all the sides of the polygon have equal lengths and all the angles of the polygon have equal measures. In other words, a regular polygon is a symmetrical shape with uniform sides and angles.Rate this question:

Lines that are on the same plane and never meet or intersect are called perpendicular lines.
-
True
-
False
Correct Answer
A. FalseExplanation
Perpendicular lines are not lines that are on the same plane and never meet or intersect. Perpendicular lines are lines that intersect at a 90-degree angle. Therefore, the statement is false.Rate this question:

-
Figure 1
-
Figure 2
-
Figure 3
-
Figure 4
Correct Answer
A. Figure 3Explanation
In Figure 3, angle DEF is equal to 90 degrees because it forms a right angle. A right angle is a 90-degree angle, formed when two lines or line segments intersect. The other figures do not show a right angle at angle DEF, making Figure 3 the correct answer.Rate this question:

A. Figure 2Explanation
In Figure 2, angle DEF is equal to 180 degrees because it is a straight line. In geometry, a straight line forms an angle of 180 degrees, which means that the angle spans the entire length of the line. Therefore, Figure 2 is the correct answer as it shows angle DEF as a straight line.Rate this question:

A shape that has two halves that are mirror images of each other has _________________________________.
-
Rotation symmetry
-
Reflection symmetry

A shapre that looks the same when it is rotated less than a full turn has ___________________________________.
-
Rotation symmetry
-
Reflection symmetry
Correct Answer
A. Rotation symmetryExplanation
A shape that looks the same when it is rotated less than a full turn has rotation symmetry. This means that the shape can be rotated by a certain angle (less than 360 degrees) and still maintain its original appearance. The presence of rotation symmetry indicates that the shape has a balanced and harmonious design, allowing it to be visually appealing from different angles of rotation.Rate this question:

The angle sum of any triangle is _______________ degrees.
Correct Answer
180Explanation
The angle sum of any triangle is always 180 degrees. This is a fundamental property of triangles in Euclidean geometry. The sum of the interior angles of a triangle is always equal to 180 degrees, regardless of the size or shape of the triangle. This property can be proven using various geometric theorems and principles.Rate this question:

The angle sum of any quadrilateral is _______________ degrees.
Correct Answer
360Explanation
The angle sum of any quadrilateral is always 360 degrees. This is because a quadrilateral has four sides, and the sum of the interior angles of any polygon is given by the formula (n-2) * 180 degrees, where n is the number of sides. Therefore, for a quadrilateral with four sides, the sum of the interior angles is (4-2) * 180 = 360 degrees.Rate this question:
- 28.
Which is the correct formula for finding the angle sum of any polygon?
-
(# of sides - 1) x 180 = angle sum
-
(# of sides - 2) x 360 = angle sum
-
(# of sides - 2) x 180 = angle sum
-
(# of sides + 2) -180 = angle sum
Correct Answer
A. (# of sides - 2) x 180 = angle sumExplanation
The correct formula for finding the angle sum of any polygon is (# of sides - 2) x 180 = angle sum. This formula is derived from the fact that the sum of the interior angles of a polygon is equal to (n-2) times 180 degrees, where n is the number of sides of the polygon. By subtracting 2 from the number of sides and multiplying by 180, we can find the total angle sum of the polygon.Rate this question:
