Complementary, Supplementary, Vertical, Adjacent Angles

Front

What are complementary angles?

Back

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

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 equal.

Front

What are adjacent angles?

Back

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

Front

If angle A and angle B are complementary and angle A measures 30°, what is the measure of angle B?

Back

Angle B measures 60°.

Front

If angle C and angle D are supplementary and angle C measures 110°, what is the measure of angle D?

Back

Angle D measures 70°.

Front

If two angles are vertical angles and one measures 45°, what is the measure of the other angle?

Back

The other angle also measures 45°.

Front

If angle E is 40° and angle F is adjacent to angle E, what is the maximum measure angle F can be if they are complementary?

Back

Angle F can be a maximum of 50°.

Front

What equation would you use to find x if two angles are complementary and one angle is represented as 2x - 6?

Back

You would use the equation 2x - 6 + angle = 90.

Front

If angle G is 90° and angle H is adjacent to angle G, what can you say about angle H if they are supplementary?

Back

Angle H must be 90°.
