45°-45°-90° Triangle Theorem In a 45°-45°-90° triangle, the hypotenuse is times as long as the legs

Find the lengths of the sides of a 45°-45°- 90° Triangle Find the length of the hypotenuse of a triangle with leg lengths of 8. Find the length of the hypotenuse of a triangle with leg lengths of Find the length of the legs of a triangle with an hypotenuse of

30°-60°-90° Triangle Given an equilateral triangle with side lengths of 2:

30°-60°-90° Triangle Theorem In a 30°-60°-90° triangle, the hypotenuse is twice as long as the shorter leg, and the longer leg is times as long as the shorter leg

Find the lengths in a 30°-60°-90° triangle Find the length of a leg, if the shorter leg is 2, and the hypotenuse is 4. Find the length of the hypotenuse and longer leg if the shorter leg is
