What You Need To Know...

Properties of right triangles.

The benchmark will be assessed using MC (Multiple Choice) and FR (Fill in Response) items.
Items may require the use of the Pythagorean Theorem, special right triangles, and relationships involving an altitude drawn to the hypotenuse of a right triangle.
Items may require the use of the geometric mean.
Radical expressions in multiple choice options will be in simplified or rationalized form.

Example One

In Triangle Marking ABC, is an altitude.
