Description
The focus in Topic D is similarity within right triangles. Students examine how an altitude drawn from the vertex of a right triangle to the hypotenuse creates two similar sub-triangles. Students work with adding, subtracting, multiplying, and dividing radical expressions. Finally, students prove the Pythagorean Theorem using similarity.
