Question

A triangle has sides with lengths of 4 yards, 10 yards, and 11 yards. Is it a right triangle?

yes
no

Answer 1

no

Explanation:

for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse

a² + b² = c²

in this problem, 4² + 10² ≠ 11²

16 + 100 ≠ 121
