Parallel Lines cut by a Transversal Review

Front

A pair of adjacent angles whose non-common sides are opposite rays. HINT: These angles are supplementary!

Back

Linear Pair

Front

Two angles whose sum is 90 degrees.

Back

Complementary Angles

Front

Two angles whose sum is 180 degrees

Back

Supplementary Angles

Front

A pair of opposite congruent angles formed by intersecting lines.

Back

Vertical Angles

Front

-Lines that Never Intersect -Slopes are the SAME

Back

Parallel Lines

Front

Two angles that share a common vertex and side, but have no common interior points (don't overlap).

Back

Adjacent Angles

Front

A line that intersects two or more lines (usually parallel lines). Hint: Line "l" in the picture

Back

Transversal

Front

-Angles in the same place on different lines

Back

Corresponding Angles

Front

-angles between 2 lines (interior) and on opposite sides of a transversal (alternate) -CONGRUENT when lines are parallel

Back

Alternate Interior Angles

Front

-Angles that lie outside a pair of lines (exterior) and on opposite sides of a transversal (alternate.)

Back

Alternate Exterior Angles
