Which best explains why this triangle is or is not a right triangle?

erastovalidia [21]

Answer:

<h2>This triangle is a right triangle:</h2><h2>36² + 15² = 39².</h2>

Step-by-step explanation:

If a ≤ b <c is the length of the sides of a right triangle, then:

$a^2+b^2=c^2$

We have

$a=15\ in,\ b=36\ in,\ c=39\ in$

Check the equality:

$L_s=15^2+36^2=225+1296=1521$

$R_s=39^2=1521$

$L_s=R_s$

It's a right triangle.
