1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides
yes, some sides would have different measurements
This would be an isosceles triangle.
If it were, then 17 squared would equal 8 squared plus 15 squared. ie 289 would equal 64 + 225 which it does, so it is a pythagorean triangle.
False. It can't be.In a right triangle, the sum of the squares of the two short sides is equal to the squareof the longest side.122 = 144152 = 225-------------sum = 369202 = 400, not 369.So these are not the sides of a right triangle.
