Which of these four sets of side lengths will form a right triangle?Set 14 cm, 5 cm, 6 cmSet 2 8 in., 12 in., 20 in.Set 310 mm, 20 mm, 30 mmSet 412 ft, 16 ft, 20 ft

For a right triangle, the squares of the two shorter sides must add to the square of the longest side. For Set 4, 12² + 16² = 144 + 256 = 400, and 20² = 400. So Set 4 forms a right triangle.
