Answer:
No
Step-by-step explanation:
Let's plug these measurements into the Pythagorean Theorem and determine whether the resulting equation is true or not:
4^2 + 55^2 = 73^2
16 + 3025 = 5329 This is false, and so:
A triangle with side lengths 73 inches, 55 inches and 4 inches is NOT a right triangle.
