Supplement your scholars' knowledge of angles involved with parallel lines. Using the properties of alternate interior angles and linear pairs, the presenter shows interior angles located on the same side of a transversal of parallel lines must be supplementary. The resource is a portion of an extensive playlist covering basic geometry.
