Semester Review- Adjacent, Vertical, Comp, Supplementary Angles

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What is the definition of adjacent angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What are complementary angles?

Back

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

Front

If angle A and angle B are supplementary, and angle A measures 70 degrees, what is the measure of angle B?

Back

Angle B measures 110 degrees (180 - 70 = 110).

Front

If angle C and angle D are complementary, and angle C measures 30 degrees, what is the measure of angle D?

Back

Angle D measures 60 degrees (90 - 30 = 60).

Front

What is the relationship between adjacent angles?

Back

Adjacent angles share a common side and a vertex.

Front

If two angles are vertical angles, what can be said about their measures?

Back

Vertical angles are equal in measure.

Front

What is the sum of the measures of two supplementary angles?

Back

The sum of the measures of two supplementary angles is 180 degrees.

Front

What is the sum of the measures of two complementary angles?

Back

The sum of the measures of two complementary angles is 90 degrees.
