Two angles are complementary. If one measures 37°, what does the other measure?
Answer: 53°
Complementary angles sum to 90°, so 90 − 37 = 53°.
What is the measure of an angle that is supplementary to a 118° angle?
Answer: 62°
Supplementary angles sum to 180°, so 180 − 118 = 62°.
A line segment has two endpoints. What is the correct term for a part of a line that has one endpoint and extends infinitely in one direction?
Answer: Ray
A ray has exactly one endpoint and continues without end in one direction.
When two lines intersect, the angles opposite each other are called what?
Answer: Vertical angles
Vertical angles are the opposite angles formed by two intersecting lines and are always equal.
An angle measures exactly 90°. What type of angle is it?
Answer: Right angle
An angle of exactly 90° is a right angle.
Two angles form a linear pair. If one is 105°, what is the other?
Answer: 75°
A linear pair is supplementary, so 180 − 105 = 75°.
How many points are needed to determine a unique straight line?
Answer: Two
Exactly two distinct points determine one unique line.
