What is the 30°-60°-right triangle theorem?

AIn a right triangle, the hypotenuse is three times as long as a leg if and only if the measure of

the angle opposite that leg is 30°.

BIn a right triangle, the hypotenuse is twice as long as a leg if and only if the measure of the

angle opposite that leg is 60°.

CIn a right triangle, the hypotenuse is twice as long as a leg if and only if the measure of the

angle opposite that leg is 30°.

DIn an equilateral triangle, the hypotenuse is twice as long as a leg if and only if the measure of

the angle opposite that leg is 30°.
