Determine whether the statement is always true, sometimes true, or never true.
3) The length of the hypotenuse of a right triangle equals the length of one of the legs of the triangle.
Answer choice: a.) always true b.) sometimes true c.)never true

Think about this in terms of the a^2+b^2=c^2. Could a or b possibly be the same length as c?

PJ is citing the Pythagorean theorem.
(side a)^2 + (side b)^2 = hypotenuse^2
What would have to happen for either side = hypotenuse? 
you.
