Angle Pairs

Front

What is an adjacent angle?

Back

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

Front

Define complementary angles.

Back

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

Front

Define supplementary angles.

Back

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

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is a corresponding angle?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

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

Back

60 degrees (90 - 30 = 60).

Front

If angle B is 120 degrees, what is the measure of its supplementary angle?

Back

60 degrees (180 - 120 = 60).

Front

Identify the angle pair: Angles 3 and 5 are formed by two intersecting lines.

Back

Vertical angles.

Front

What is the relationship between adjacent angles?

Back

Adjacent angles share a common side and vertex, and they do not overlap.

Front

If two angles are complementary and one angle measures 25 degrees, what is the other angle?

Back

65 degrees (90 - 25 = 65).
