UNDERSTANDING ANGLES ON A TRANSVERSAL

VERTICAL ANGLES Color the vertical angles. Each set should be a different color (you will need four colors)

SAME-SIDE INTERIOR ANGLES Color the same-side interior angles. Each set should be a different color (you will need two colors)

ALTERNATE INTERIOR ANGLES Color the alternate interior angles. Each set should be a different color (you will need two colors)

CORRESPONDING ANGLES Color the corresponding angles. Each set should be a different color (you will need four colors)

SUPPLEMENTARY ANGLES Color the supplementary angles. Each set should be a different color (you will need eight colors)

ALTERNATE EXTERIOR ANGLES Color the alternate exterior angles. Each set should be a different color (you will need two colors)

Angles are opposite each other when 2 lines cross. Angles are congruent.

Angles are on the same side of the transversal, and inside the parallel lines. Angle measures add up to 180 degrees.

Angles are on opposite sides of the transversal, and inside the parallel lines. Angles are congruent.

Same side of the transversal, and matching angles. Same relative position. Angles are congruent.

Two angles that create a straight line (180 degrees) Angles are on opposite sides of the transversal, and outside the parallel lines. Angles are congruent.
