Question

Can you form a right triangle with the three lengths given? Why or why not? 7 in., 24 in., 25 in.

Answer 1

Recall that using the pythaogorean theorem, which is only for right-triangles, the longest leg squared is the sum of the other two squared, namely c² = a² + b², now, if those units above are of a right triangle, then 25² = 7² + 24².

do they check out? if they do, then yes, you can make a right-triangle, if not, they nope.
