Question

Can the measures of 10 inches, 11 inches and 12 inches form a right triangle? Explain your answer. *

Answer 1

No

Explanation:

The only arithmetic sequence of side lengths that will form a right triangle is (3, 4, 5) or some multiple of that, such as (9, 12, 15).

Sides of length 10, 11, 12 cannot form a right triangle.
