using the Pythagorean theorem we can tell if it is a right triangle.
the formula is a^2 + b^2 = c^2
a =9
b =12
c=15
9^2 + 12^2 = 81 + 144 = 225
15^2 = 225
225 = 225 so it is a right triangle
the answer is TRUE

if right triangle then c^2 = a^2 + b^2
c^2 = 25^2 = 625
a^2 + b^2 = 9^2 + 12^2 = 81 + 144 = 225
SO
c^2 = a^2 + b^2
225 = 225
Conclusion: Yes, triangle LMN is a right triangle.
