### two angles that are supplementary are always linear pairs

Since r and s are parallel, the slope of r is equal to the slope of s. Since t is a straight line, the slope of t is the same at both intersections, by the definition of a straight line. Supplementary angles: Two angles that add up to 180° (or a straight angle) are supplementary. Corresponding angles are pairs of angles that lie on the same side of the transversal in matching corners. Such angles are also known as supplementary angles.
