Front

What are Adjacent Angles?

Back

Angles that share a common vertex and a common side, but do not overlap.

Front

What are Linear Pair Angles?

Back

Two adjacent angles whose non-common sides form a straight line, adding up to 180 degrees.

Front

What are Complementary Angles?

Back

Two angles that add up to 90 degrees.

Front

What are Supplementary Angles?

Back

Two angles that add up to 180 degrees.

Front

What are Vertical Angles?

Back
