Unit 2 Angle, Lines, & Proofs: Proofs Review

Front

What is the Multiplication Property of Equality?

Back

If a = b, then a * c = b * c for any number c.

Front

What does the Vertical Angles Theorem state?

Back

Vertical angles are equal.

Front

What is the Substitution Property?

Back

If a = b, then b can be substituted for a in any expression.

Front

What does the Corresponding Angles Postulate state?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

What is the definition of a linear pair?

Back

A linear pair is a pair of adjacent angles whose non-common sides form a straight line.

Front

What is the Alternate Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of alternate interior angles is equal.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines cross.

Front

What is the Transitive Property of Equality?

Back

If a = b and b = c, then a = c.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others.

Front

What does the Same Side Interior Angles Theorem state?

Back

If two parallel lines are cut by a transversal, then each pair of same side interior angles is supplementary.
