Corresponding pair of angles comprises of one exterior angle and another interior angle. Same-side exterior angles: Angles 1 and 7 (and 2 and 8) are called same-side exterior angles — they’re on the same side of the transversal, and they’re outside the parallel lines. Alternate exterior Angles. The green shaded angles are: (1) inside (between) the two parallel lines, (2) congruent (identical or the same), and (3) on opposite sides of the transversal. Again the word "alternate" means they are on opposite sides of the transversal, and "exterior" means the are not between the parallel lines (they are "outside"). Consecutive interior angles. The word equal is often used in place of congruent for these objects. Same-side interior angles are NOT always congruent. Same-side tells us that both angles are on the same side of the transversal line, and exterior tells us that both angles are exterior, or outside, of the parallel lines. Same-Side Exterior Angles. In a rectangle, if you take any two angles, they both equal 90˚ and are still supplementary, or sum up to 180˚, since it is a parallelogram and has four right angles. Two triangles are congruent when the three sides and the three angles of one triangle have the same measurements as three sides and three angles of another triangle.
