On a test I was given 2 triangles. One triangle gave measurements of all three sides as 2, 4, and 5. The next triangle had sides given 4 and 8 and it asked what the third side should be if the triangles were perpendicular.

How would I solve this? Do I find the perimeter of each triangle?

1 answer

2 * 2 = 4
4 * 2 = 8
5 * 2 = ?
