Geometry Angles Practice

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent (equal in measure).

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What does it mean if two angles are congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the definition of adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

If angle A and angle B are supplementary, what is the equation that represents their relationship?

Back

A + B = 180 degrees.

Front

If angle A is 30 degrees, what is the measure of its complementary angle?

Back

The complementary angle is 60 degrees (90 - 30 = 60).

Front

What do hatch marks on angles indicate?

Back

Hatch marks indicate that the angles are congruent (equal in measure).

Front

What is the equation to find the measure of angle x if x + 8 = 141?

Back

To find x, subtract 8 from 141: x = 141 - 8, so x = 133.

Front

What is the sum of the measures of two angles that are complementary?

Back

The sum is 90 degrees.
