Poor – Pythagorean Theorem and its Converse Review

Not good. I would adjust the naming of the triangle to triangle red. The refer to the sides as a,b,c. This will help clear a distinction between the name and the sides. Also, I dislike that the app uses a strange formula instead of the common/most widely used form of a^2+b^2=c^2. Your formula isn't good for classroom or review purposes. Add a lesson about what is a right triangle. This is a good link to help students start learning about this concept.
