Special Right Triangles In a degrees right triangle both legs are congruent and the hypotenuse is the length of the leg times

Triangle In a triangle, the length of the hypotenuse is  2 times the length of one leg. x x x Another way of stating the formula

Example Determine the length of each side of the following triangle n w

Find the length of each side √2 8  2 n w

Find the length of each side. The hypotenuse is n w

Find the length of each Variable This is a triangle. x 3 y

triangle In a right triangle this is the format x2x x Hypotenuse = 2 Adjacent to 30 = Adjacent to 60 = 1

Triangles In a triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is  3 times the length of the shorter leg. x x  3 2x 30  60  Another way of stating the formula

Example Determine the length of each side of the following triangle n w

Find the length of each variable y x 5 √ 3 5 

Find the length of each side n w

Find the length of each variable r s
