A triangle has sides with lengths of 60 feet, 63 feet, and 87 feet. Is it a right triangle?

Sedaia [141]

Answer:

Yes

Step-by-step explanation:

We can use the Pythagorean Theorem to check if this triangle is a right triangle:

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

Note that $a$ and $b$ are the legs of the triangle and $c$ is the hypotenuse:

Substitute the lengths of the sides into the equation:

$60^2+63^2=87^2$

$3600+3969=7569\\7569=7569$

Therefore this triangle is a right triangle.
