ACCESS - Consecutive Angles of a trapezoid
Figure ABDC is a trapezoid. Lines a and b are parallel lines extended out from the bases. Lines c and d are transversals that intersect the parallel lines and are extensions of the legs of the trapezoid. Drag points A, B, and C to manipulate the trapezoid. 1. How does this affect the measures of the consecutive angles? 2. Does their sum ever change? Note: Consecutive angle pairs are color coded in blue and red. Use the toggle to turn extra elements on or off as needed.
