adjacent angles

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 the sum of angles on a straight line?

Back

The sum of angles on a straight line is 180°.

Front

If angle A is 75°, what is the measure of its adjacent angle on a straight line?

Back

The adjacent angle would be 105° because 180° - 75° = 105°.

Front

What is a straight angle?

Back

A straight angle is an angle that measures exactly 180°.

Front

If angle OMJ measures 36° and angle JMK measures 125°, what is the measure of angle OMK?

Back

The measure of angle OMK is 161° because 36° + 125° = 161°.

Front

What is the measure of angle A if it is a straight angle?

Back

Angle A measures 180°.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of complementary angles is 90°.

Front

If angle A is 45°, what is the measure of its adjacent angle on a straight line?

Back

The adjacent angle would be 135° because 180° - 45° = 135°.

Front

What is the relationship between adjacent angles?

Back

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

Front

If angle A measures 30°, what is the measure of its adjacent angle on a straight line?

Back

The adjacent angle would be 150° because 180° - 30° = 150°.
