Front

What are adjacent angles?

Back

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

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles whose non-common sides form a straight line.

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 the definition of an angle?

Back

An angle is formed by two rays that meet at a single endpoint, called the vertex.

Front

Solve for x: 2x + 8 = 28

Back

x = 10

Front

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

Back

The complement of angle A is 60 degrees.

Front

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

Back

The supplement of angle B is 60 degrees.

Front

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

Back

The sum of the measures of angles in a triangle is always 180 degrees.
