Question

A triangle has sides with lengths of 21 meters, 70 meters, and 73 meters. Is it a right triangle?

Answer 1

9514 1404 393

Answer:

no

Explanation:

It is close, but not exactly a right triangle.

If it were a right triangle, we would have ...

21² +70² = 73²

We have instead ...

441 +4900 ≠ 5329

5341 ≠ 5329 . . . . . . . . not a right triangle
