Question

A triangle has sides that measure 5 units, 7 units, and 8 units. Is this a right triangle

Answer 1

No

Explanation:

Using the given lengths if we say this is a right triangle then 8 would be length of hypotenuse

From the Pythagorean theorem

8^2 = 5^2 + 7^2

64 = 25 + 49

64 = 74 is not a correct equation so the triangle is not a right triangle for the given lengths
