A triangle has side lengths of 7, 10, and 12. Is the triangle a right triangle?

A) Yes

B) No

No it is not because c square = a square + b square

The triangle that has side lengths of 7, 10, and 12 is not a right triangle. The correct answer is B. No.

The reason for this can be found in the Pythagorean theorem, which is a2 + b2 = c2 (this number 2 means square)

So, let's test this.

7*7 + 10*10 = 12*12

49+100 = 144

149 = 144

Since this is not equal, this isn't a right triangle.
