2.04 Side Splitter Theorem Exploration
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
Summarize what you've observed. When line DE splits the two sides of triangle ABC and is parallel with side AB, what happens?
