Consider the following triangle ABC.
If AC = 15, AB = 20, and BC = 25, and AD is perpendicular to BC, find the length AD. Try to come up with a few different methods!
We will be talking about right triangles and the Pythagorean Theorem in Session 2. Please come to the workshop with a favorite proof of Pythagoras in mind, or an activity or approach you use with students when you work with right triangles.
