Front

What are linear pair angles?

Back

Linear pair angles are two adjacent angles that form a straight line and add up to 180 degrees.

Front

If two angles are vertical angles, what can we say about their measures?

Back

Vertical angles are always congruent (equal measures).

Front

What is the definition of congruent angles?

Back
