Geometry

2. 45°-45°-90° Triangle Theorem In a 45°-45°-90° triangle, both legs are congruent and the length of the hypotenuse is 2 times the length of the leg.
hypotenuse = 2 • leg

3. Ex. 1) Find the value of each hypotenuse.

4. Ex. 2) Find the value of each leg.

5. Ex. 3) A high school softball diamond is a square
Ex. 3) A high school softball diamond is a square. The distance from base to base is 60 feet. How far does a catcher throw the ball from home plate to 2nd base?

6. 30°-60°-90° Triangle Theorem In a 30°-60°-90° triangle, the length of the hypotenuse is twice the length of the shorter leg. The length of the longer leg is 3 times the length of the shorter leg.
hypotenuse = 2 • short leg
longer leg = 3 • short leg
