Yes, the triangle with side lengths 5, 12, and 15 is a right triangle. We can verify this using the Pythagorean theorem.
a = 5, b = 12, c = 15
a^2 + b^2 = c^2
5^2 + 12^2 = 25 + 144 = 169
c^2 = 15^2 = 225
Since a^2 + b^2 = c^2, the triangle is a right triangle.
In A right triangle a^2+b^2=c^2?(where c is the length of the hypotenuse and a and b are the other two side lengths). Of a triangle has side lengths 5, 12 and 15, is the triangle a right triangle? why or why not
