Question

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?

Answer 1

Are you sure the word you're looking for is perpendicular? Perpendicular means at a 90° angle, which in your case, would mean the two triangles would be exactly the same. Did you mean mathematically similar? Because if so, I can tell you that the third side would be 10, using scale factor.
