Side Splitter Exploration

Author:Sina Baldwin, Mr. Lietzow
Below is a simple diagram with line AB, point C, and point D on segment AC. Take a moment to drag the points around to see how it behaves. Now use the checkboxes to: 1) create a parallel line through D 2) measure distances AD, CD, BE, CE 3) compare the ratios AD/CD and BE/CE
