each triangle has a base of the same length and the [b]point[/b] opposite the base is the only difference in each triangle.
Use the available [b]point[/b] on each triangle to find the differences. 1.) Create an hypothesis as to how each triangle, or point was constructed (i.e. what are the restrictions on the one free point)? 2.) Which triangles always have constant area? 3.) Which triangles can be made into right triangles?
