Same-side interior angles are supplementary. This means that when two parallel lines are cut by a transversal, the same-side interior angles formed on the same side of the transversal add up to 180 degrees.

Alternate interior angles are congruent when two parallel lines are cut by a transversal. This means that the alternate interior angles are equal in measure.

Alternate exterior angles are congruent when two parallel lines are cut by a transversal. This means that the alternate exterior angles are equal in measure.

The property you are using in the statement "if \( LM = 7 \) and \( EF + LM = NP \), then \( EF + 7 = NP \)" is known as the **Substitution Property of Equality**.

This property states that if two quantities are equal, one can be substituted for the other in any equation or expression. In this case, you are substituting \( LM \) with its value \( 7 \) in the equation \( EF + LM = NP \).
