When a pair of parallel lines meet an intersecting transversal, pairs of angles with particular properties are made. Corresponding angles are equal. The lines make an F shape. Notice that the F ...

An easy way to remember congruent angles is to relate the word "congruent" and to how that term is used in reference to parallel lines: Two parallel lines with the same measure are congruent.

Parallel lines are indicated by arrows going in the same direction. If there is more than one set of parallel lines in a diagram, different numbers of arrows are used. The three lines in this ...
