Answer:
Yes, it is a right triangle.
Step-by-step explanation:
A right triangle follows the rules of 3,4,5 side lengths, in which 5 is the hypotenuse, 3 is the shortest side, and 4 is the opposite side.
Plug it into the equation. The equation you will use is:
(shortest side)² + (longer side)² = (hypotenuse)²
(9)² + (40)² = (41)²
Simplify. First, solve the power:
(81) + (1600) = (1681)
Simplify. Combine like terms:
(81 + 1600) = 1681
1681 = 1681 (True)
Yes, these sides can be used to make a right triangle.
