Question

Two congruent right triangles with sides of 3, 4, 5 are placed together so that one pair of corresponding sides touch and the resulting figure is another triangle. What would be the perimeter of the resulting triangle?

Answer 1

it depends on which pair of the sides are touched.. if the 4s are touched then the perimeter would be 5+5+3+3=16, if the 3s are touched then the perimeter would be 5+5+4+4=18 but if the 5s are touched then it becomes a rectangle so that's irrelevant
