Question

A triangle has sides with lengths of 45 feet, 76 feet, and 90 feet. Is it a right triangle?

Answer 1

Answer:

NO

Step-by-step explanation:

Longest side of the triangle has the length = 90 feet

Other two sides are 45 feet and 76 feet

If the triangle is a right triangle then square of the longest side is equal to the sum of squares of the other two sides.

=> $\[90^{2} = 45^{2} + 76^{2}\]$

Left Hand Side = $\[90^{2}\]$ = 8100

Right Hand Side = $\[45^{2} + 76^{2}\]$

= 2025 + 5776

= 7801

So the left hand side is not equal to right hand side. The condition for right triangle is NOT satisfied.
