Which of the following is not an Undefined Term?
- A.
Point
- B.
Line
- C.
Segment
- D.
Plane
Correct Answer
C. SegmentExplanation
A segment is not an Undefined Term because it has a specific definition in geometry. A segment is a part of a line that consists of two endpoints and all the points between them. In contrast, a point, line, and plane are all examples of Undefined Terms in geometry because they are basic concepts that are not defined or explained further.Rate this question:

What is the measurement of the missing angle?
- A.
54°
- B.
68°
- C.
122°
- D.
126°
Correct Answer
D. 126°Explanation
The sum of the three angles inside the triangle is 180°.
The third angle will then be = 180 - 58 - 68 = 54°.
Now, x + 54° = 180°
x = 126°
Therefore, the missing angle would be 126°.Rate this question:

What is the complementary angle of 46°?
- A.
54°
- B.
44°
- C.
134°
- D.
144°
Correct Answer
B. 44°Explanation
The complementary angle of an angle is the angle that, when added to the given angle, results in a sum of 90 degrees. In this case, the complementary angle of 46 degrees is 44 degrees because 46 + 44 = 90 degrees.Rate this question:

What is the supplementary angle of 22°?
- A.
158°
- B.
168°
- C.
68°
- D.
78°
Correct Answer
A. 158°Explanation
The supplementary angle of a given angle is the angle that, when added to the given angle, results in a sum of 180 degrees. In this case, the given angle is 22 degrees. To find the supplementary angle, we subtract the given angle from 180 degrees: 180 - 22 = 158 degrees. Therefore, the supplementary angle of 22 degrees is 158 degrees.Rate this question:

Which of the following points are coplanar?
- A.
A, B and D
- B.
D and B
- C.
A, B and C
- D.
F, D and B
Correct Answer
C. A, B and CExplanation
The points A, B, and C are coplanar because they all lie on the same plane. A plane is a two-dimensional flat surface that extends infinitely in all directions. Therefore, if three points lie on the same plane, they are coplanar.Rate this question:

The guitar string is an example of a?
- A.
Point
- B.
Angle
- C.
Plane
- D.
Line
Correct Answer
D. LineExplanation
The guitar string is an example of a line because it is a long, thin object that extends indefinitely in both directions. It has one dimension, length, and does not have any width or depth. The guitar string can be represented mathematically as a straight line, and it is often used to produce musical notes by vibrating in a linear fashion.Rate this question:

Two distinct rays that have the same vertex and which lie on the same line are called ________________
- A.
Collinear rays
- B.
Coplanar rays
- C.
Opposite rays
- D.
Rays
Correct Answer
C. Opposite raysExplanation
Two distinct rays sharing the same vertex and lying on the same line are known as "opposite rays" or "opposite vectors." These rays extend indefinitely in opposite directions from the common endpoint, forming a straight line.Rate this question:

The following are the possible ways to name the angle except one
- A.
Angle ABC
- B.
Angle BAC
- C.
Angle CBA
- D.
Angle B
Correct Answer
B. Angle BACExplanation
The given options are all possible ways to name an angle formed by three points A, B, and C, except for "angle BAC". This is because when naming an angle, the vertex (in this case, point A) should always be in the middle. The correct way to name the angle formed by points A, B, and C is "angle ABC".Rate this question:

Is a segment that divides any angle of a triangle into two angles of equal measures
- A.
Altitude
- B.
Median
- C.
Vertex
- D.
Angle Bisector
Correct Answer
D. Angle BisectorExplanation
An angle bisector is a segment that divides any angle of a triangle into two angles of equal measures. It is a line that cuts an angle in half, creating two smaller angles that have the same measure. In the context of a triangle, an angle bisector starts from a vertex and divides the opposite side into two segments that are proportional to the adjacent sides.Rate this question:

Which of the statements is correct
- A.
Rectangles are rhombuses
- B.
A rectangle is a rhombus
- C.
All squares are rectangles
- D.
All rectangles are squares
Correct Answer
C. All squares are rectanglesExplanation
The statement "all squares are rectangles" is correct because a square is a special type of rectangle. A rectangle is defined as a quadrilateral with four right angles, and a square meets this definition as it has four right angles. Additionally, a square also has the additional property of having all sides equal in length, which makes it a special case of a rectangle. Therefore, all squares can be classified as rectangles, but not all rectangles can be classified as squares.Rate this question:

In the figure, line DE is a _____________ ?
- A.
Secant
- B.
Tangent
- C.
Chord
- D.
Minor Arc
Correct Answer
C. ChordExplanation
In the given figure, line DE intersects the circle at two points, creating a segment within the circle. This segment is known as a chord. Therefore, the correct answer is chord.Rate this question:

In the figure, Line PAQ is a ___________?
- A.
Secant
- B.
Tangent
- C.
Chord
- D.
Minor Arc
Correct Answer
B. TangentExplanation
In the given figure, Line PAQ is a tangent. A tangent is a line that touches a curve at only one point and is perpendicular to the radius at that point. In this case, line PAQ touches the curve at point A and is perpendicular to the radius at that point. Therefore, it can be concluded that line PAQ is a tangent.Rate this question:

Two planes intersect at a common _________?
- A.
Point
- B.
Line
- C.
Plane
- D.
Angle
Correct Answer
B. LineExplanation
When two planes intersect, they form a line. This is because a plane is a two-dimensional surface, and when two planes intersect, they create a common boundary or edge, which is a one-dimensional object known as a line. Therefore, the correct answer is "Line."Rate this question:

Comes from the two Greek words geo and metron which mean 'Earth' and 'to measure'
- A.
Algebra
- B.
Geometry
- C.
Measurement
- D.
Statistics
Correct Answer
B. GeometryExplanation
Geometry comes from the two Greek words geo and metron which mean 'Earth' and 'to measure'. This suggests that geometry is the branch of mathematics that deals with the measurement and properties of shapes, figures, and spaces. It involves studying the relationships and properties of points, lines, angles, surfaces, and solids.Rate this question:

These lines go on forever, but they never meet. What are they?
- A.
Parallel Lines
- B.
Intersecting Lines
- C.
Perpendicular Lines
- D.
Skew Lines
Correct Answer
A. Parallel LinesExplanation
Parallel lines are lines that are always the same distance apart and never intersect. They continue indefinitely in the same direction, never meeting or crossing each other. This is why they are described as going on forever but never meeting.Rate this question:

What is the degree of a straight line?
- A.
45°
- B.
90°
- C.
180°
- D.
360°
Correct Answer
C. 180°Explanation
The degree of a straight line is 180° because a straight line forms a straight angle, which is a line that measures 180°. In geometry, a straight line is the shortest distance between two points and it does not bend or curve. Therefore, the angle formed by a straight line is always 180°.Rate this question:

A point in a plane can have how many lines going through it?
- A.
One
- B.
None
- C.
Exactly two
- D.
Infinite
Correct Answer
D. InfiniteExplanation
A point in a plane can have an infinite number of lines going through it because there are an infinite number of possible directions in which a line can be drawn in a plane. Regardless of the position or orientation of the point, there will always be an infinite number of lines that can pass through it.Rate this question:

An obtuse angle is ______________
- A.
Between 0 and 90 degrees
- B.
Between 90 and 180 degrees
- C.
90 degrees
- D.
Between 180 and 360 degrees
Correct Answer
B. Between 90 and 180 degreesExplanation
An obtuse angle is a type of angle that measures between 90 and 180 degrees. It is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees).Rate this question:
