Parallel Line Side Splitter Theorem (Corollary)
Given: line AB || line HG || line EF. What do you notice about how the two transversals have been cut by the three parallel lines? Click and drag points C and/or D to move the parallel lines up and down, click and drag points A or B to change the slopes of the parallel lines and test your conjecture.
Write your conjecture about how the two transversals are cut by the three parallel lines here.
