7.G.5 Flashcard

Front

What are vertical angles?

Back

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

Front

What is the sum of supplementary angles?

Back

The sum of supplementary angles is 180 degrees.

Front

If angles AOD and BOC are equivalent, what is the measure of angle AOB if AOD measures 112 degrees?

Back

Angle AOB measures 112 degrees.

Front

What is the angle that is supplementary to 174.2 degrees?

Back

The angle that is supplementary to 174.2 degrees is 5.8 degrees.

Front

What are complementary angles?

Back

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

Front

What are the pairs of vertical angles formed by intersecting lines?

Back

Pairs of vertical angles are formed by the angles that are opposite each other at the intersection.

Front

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

Back

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

Front

What is the relationship between adjacent angles formed by intersecting lines?

Back

Adjacent angles share a common side and vertex and are next to each other.

Front

If two angles are supplementary and one angle measures 70 degrees, what is the measure of the other angle?

Back

The other angle measures 110 degrees (180 - 70 = 110).

Front

What is the measure of each angle if two angles are vertical and one measures 45 degrees?

Back

The other angle also measures 45 degrees because vertical angles are equal.
