3-4-5, 5-12-13, 8-15-17 triangles

If we are told that the sides of a triangle are one of the right triangle ratios (ex: 3-4-5), can we always assume its a right triangle? Or is it possible to have a non-right triagle with those measurements?

hi... a rt triangle measurements such as 3,4,5, have to always include a 90 degree ... firstly cos of pythagorous theorem which is perpedicular sq. + base sq.= hypotenuese sq.

also this can be proven by trignometry... in short the answer is YES.

Thank you karan; that is correct.
