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

If two angles are adjacent, what can you say about their measures?

Back

The measures of adjacent angles can be added together to find the total measure of the angle formed by their non-common sides.

Front

What is the sum of the measures of two adjacent angles if one angle measures 80°?

Back

If one angle measures 80°, the sum of the two adjacent angles depends on the measure of the second angle.

Front

Calculate the missing angle if one adjacent angle is 45° and the total angle is 90°.

Back

The missing angle is 90° - 45° = 45°.

Front

What is the measure of angle A if angle B is 148° and they are adjacent?

Back

Angle A can be any measure that, when added to 148°, does not exceed 360°.

Front

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

Back

Angle OMK = 36° + 125° = 161°.

Front

Find the missing angle if one adjacent angle is 80° and they form a straight line.

Back

The missing angle is 180° - 80° = 100°.

Front

What do you call two angles that add up to 90°?

Back

Two angles that add up to 90° are called complementary angles.

Front

What do you call two angles that add up to 180°?

Back

Two angles that add up to 180° are called supplementary angles.

Front

If angle A is 90° and angle B is adjacent to it, what can you say about angle B?

Back

Angle B can be any angle that, when added to 90°, does not exceed 180°.
