How do you determine if the lengths #36, 77, 85# form a right triangle?
Use the Pythagorean theorem. See the entire determination process below:
We will use the Pythagorean Theorem to determine if these lengths for a right triangle.
This theorem states, for a right triangle:
Substitute the values into this equation and see if both sides of the equation are equal. If they are the lengths form a right triangle. If they are not equal then they would not form a right triangle.
Because both sides of the equation are equal these lengths do form a right triangle.
