2nd pd Supplementary Angles and Vertical Angles

Front

What are Supplementary Angles?

Back

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

Front

If m∠1 = 30°, what is m∠3 if they are vertical angles?

Back

m∠3 = 30° (Vertical angles are equal).

Front

Find the value of x if the angles are supplementary and one angle is 160°.

Back

x = 20° (180° - 160° = 20°).

Front

What is the measure of angle A if it is supplementary to 100°?

Back

Angle A = 80° (180° - 100° = 80°).

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are always equal.

Front

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

Back

The sum of complementary angles is 90 degrees.

Front

What is the measure of an angle that is supplementary to 90°?

Back

The angle measures 90° (180° - 90° = 90°).

Front

If m∠2 = 60°, what is m∠4 if they are vertical angles?

Back

m∠4 = 60° (Vertical angles are equal).

Front

What is the relationship between supplementary angles and a straight line?

Back

Supplementary angles form a straight line when added together.

Front

If one angle measures 150°, what is the measure of its supplementary angle?

Back

The supplementary angle measures 30° (180° - 150° = 30°).
