### How do you find the hypotenuse of a non right triangle?

By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.

### Can there be a equilateral right triangle?
