Front

What are adjacent angles?

Back

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

Front

What are vertical angles?

Back

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

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

True or False? Angles a & b are adjacent angles if they share a common vertex and a common side.

Back

True

Front

True or False? Vertical angles are always adjacent angles.

Back

False

Front

If two angles are complementary and one angle measures 30 degrees, what is the measure of the other angle?

Back

60 degrees.

Front

If two angles are supplementary and one angle measures 110 degrees, what is the measure of the other angle?

Back

70 degrees.

Front

What is the sum of the measures of angles in a triangle?

Back

180 degrees.

Front

What is the measure of each angle in a right triangle?

Back

One angle measures 90 degrees, and the other two angles add up to 90 degrees.
