How to Use

Use the red points to adjust Triangle ABC.

Buttons

• The buttons are meant to be shown sequentially.
  
  • The Show/Hide Distances and Show/Hide Lengths will provide measurements that can be toggled on and off.
• At any time, you can press the Reset button to start over.

Before using any of the buttons, explore the following:

• How many points of concurrency does a triangle have? What are they, and how do you construct them?
  • Is it possible for any of these points to live outside of the triangle?
  • If possible, when are two or more of these points in the same location?
  • What is/are the relationship(s) between the measurements of these points, if any?
