Answer:
It would result in a right triangle
Step-by-step explanation:
To prove if it's a right triangle, substitute the given dimensions into the formula of the Pythagorean Theorem ([tex]a^{2} + b^{2} = c^{2}[/tex]) and if both sides are equal, its a right triangle:
[tex]9^{2} + 12^{2} = 15^{2}[/tex]
81 + 144 = 225
225 = 225
