The longer leg of a 30 - 60 - 90 triangle is twice as long of its hypotenuse.

Answer 1

both legs of a right triangle are shorter than the hypotenuse

You must mean the shorter leg of the 30 60 90 right triangle is half the length of the hypotenuse.

It's the side oppposite the 30 degree angle.

The longer leg is opposite the 60 degree angle and is (sqr3)/2 times the length of the hypotenuse.

The hypotenuse is opposite the 90 degree angle. It's twice as long as the shorter leg, and 2/sqr3 times as long as the longer leg

the 3 angles, 30 60 90 correspond to sides in the ratio 1, sqr3, 2, If you want to know the actual lengths, you need more information
