# Math Help - Proving the side in a triangle is half as long as the hypotenuse.

1. ## Proving the side in a triangle is half as long as the hypotenuse.

Prove that in a right triangle with a 30 degree angle, the side opposite that angle is half as long as the hypotenuse. Thanks.

2. Block the triangle with a circle, the circle radius is c/2(why?)... now what?

3. Hello, RoyJones!

Prove that in a right triangle with a 30 degree angle,
the side opposite that angle is half as long as the hypotenuse.

Draw an equilateral triangle with an altitude.
The proof should be obvious.
