Angle Types

Front

What are 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 congruent.

Front

What is the sum of the angles in a triangle?

Back

The sum of all three angles in a triangle is always 180 degrees.

Front

What are complementary angles?

Back

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

Front

If angle A is 40 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 140 degrees.

Front

If angle 1 is 62 degrees, what is the measure of angle 2 if they are supplementary?

Back

Angle 2 is 118 degrees.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the measure of a straight angle?

Back

A straight angle measures 180 degrees.

Front

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

Back

The other angle measures 60 degrees.

Front

What is the relationship between adjacent angles?

Back

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