Using the Pythagorean Theorem, is a triangle with sides abc a right triangle? #a=12, b=9, c=15#
Yes. It’s a right triangle.
As per Pythagoras theorem,
If the sides are in the ratio 3 : 4 : 5, then the triangle is a right triangle.
In the given sum, sides are in the ratio, 9 : 12 : 15 which is equivalent to 3 : 4 : 5.
Hence it’s aright triangle as per Pythagoras theorem.
