Does 4,8,12 form a right triangle?

No, side lengths of 4, 8, and 12 do not form a right triangle.

Step-by-step explanation:

According to the Pythagorean Theorem, a² + b² = c².

In this theorem, "c²" represents the largest side (c) squared. So, this means that the two smaller sides squared must be equal to the largest side squared.

4² + 8² = 12²

16 + 64 = 144

80 ≠ 144

Yes it does form a right triangle i've learned this in pre cal math grade 11
