Question

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

A. In 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°.

B. In 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°.

C. In 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°.

D. In 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°.

Answer 1

C

Answer 2

What is the hypotenuse-leg theorem?

A. If the hypotenuse of a right triangle is congruent to the corresponding part of another right triangle, then the triangles are congruent.

B. If the hypotenuse and one leg of a right triangle are congruent to the corresponding parts of another right triangle, then the triangles are congruent.

C. If the hypotenuse and one leg of a right triangle are similar to the corresponding parts of another right triangle, then the triangles are congruent.

Answer 3

B

Answer 4

C. In 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°.
