Special Right Triangles Objective: SWBAT calculate the value of each side of a right triangle by using the Theorem to find the missing sides of 2 given right triangles.

Label the side of the triangle:

5 Hypotenuse = Long Leg = Model:

√3 x Hypotenuse = Short Leg = Long Leg =

Solve for missing sides. 4 Structured Practice :

18 x y

Instructions: Use a whiteboard to show your work. Discuss with your group the procedure used to solve it Share with other groups..
