Identify pairs of angles formed by parallel lines and a transversal.
Parallel Lines: Two lines that never intersect
Transversal: Line that intersects two parallel lines
Alternate Interior Angles: Two angles on the opposite side of the transversal, inside the parallel lines
Corresponding Angles: Two congruent angles on the same side of the transversal
Alternate Exterior Angles: Two angles on the opposite side of the transversal, outside of the parallel lines
Consecutive Angles: supplementary angles inside of the parallel lines, on the same side as the transversal, also called same-side interior
Vertical Angles: Congruent angles across from each other, formed by two intersecting lines.
Straight Angle: a straight line, 180º
