Follow the directions on your page to fill in your table.
  1. Move C so that angle A is an acute angle (but different from your neighbor). Record in your table.
  2. Record the distances of DE, AE, and AD.
  3. Calculate the ratios DE/AD, AE/AD, and DE/AE.
  4. Drag D along AC. What happens to the measure of ∠A as D moves? Repeat steps 2 and 3.
  5. Drag D to a third location along AC. Repeat steps 2 and 3.
