Question

Does 25 16 12 make a right triangle​

Answer 1

Answer:

The given lengths do not make a right triangle

Step-by-step explanation:

A right triangle has the sum of the squares of the side lengths equal to the square of the hypotenuse, per the Pythagorean Theorem:

$a^2+b^2=c^2\\\\12^2+16^2\stackrel{?}{=}25^2\\\\144+256\stackrel{?}{=}625\\\\400\stackrel{?}{=}625\\\\400\neq625$

Since the sum of the squares of the side lengths are not equal to the square of the hypotenuse, then the lengths of the triangle don't make a right triangle.
