Pythagorean Theorem Facts (8.1) ◦ We use the Pythagorean theorem to: ◦ Solve for a missing side of a right triangle (if I know the other 2 sides) ◦ Decide if a triangle is acute, obtuse or right ◦ Find the distance between two points on a grid by creating a triangle with horizontal and vertical distances

Special Right Triangle Facts (8.2) ◦ We use special right triangles when: ◦ We have either a or triangle ◦ We are looking for 1 or 2 missing sides (and 1 side is given)

Trigonometry Facts (8.3 and 8.4) ◦ We use to solve for missing SIDES or ANGLES in a right triangle if you are given either a SIDE and an ANGLE or 2 SIDES. ◦ Sine ◦ Cosine ◦ Tangent ◦ Secant ◦ Cosecant ◦ Cotangent
