Question

3) A triangular piece of glass has sides that measure 18 in., 19 in., and 25 in. Is the piece of glass in the shape of a right triangle ? Explain.

Answer 1

If the triangle is a right triangle then

18 ^ 2 + 19^ 2 = 25 ^2

324 + 361 = 685 which is NOT 25^2 (or 625)

It is NOT a right triangle
