Complementary, Supplementary, Adjacent, Vertical 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 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 Adjacent Angles?

Back

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

Front

If one angle measures 30 degrees, what is the measure of its complementary angle?

Back

60 degrees.

Front

If one angle measures 110 degrees, what is the measure of its supplementary angle?

Back

70 degrees.

Front

What is the measure of a right angle?

Back

90 degrees.

Front

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

Back

45 degrees.

Front

If two angles are supplementary and one measures 120 degrees, what is the measure of the other angle?

Back

60 degrees.

If two angles are complementary and one measures 25 degrees, what is the measure of the other angle?

Back

65 degrees.
