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