could 9 in, 12 in, 15 in be the sides of a right triangle

1 answer

To determine if 9 in, 12 in, and 15 in could be the sides of a right triangle, we can check if the Pythagorean theorem holds true for these values. According to the Pythagorean theorem:

a^2 + b^2 = c^2

Where a and b are the lengths of the two legs of a right triangle, and c is the length of the hypotenuse.

Let's substitute the given values:

9^2 + 12^2 = 15^2
81 + 144 = 225

Simplifying the equation:

225 = 225

Since the equation holds true, we can conclude that 9 in, 12 in, and 15 in could be the sides of a right triangle.
