Answer:
No
Step-by-step explanation:
This is not a right triangle.
The longest side (23) would need to be the hypotenuse, and the two other shorter sides (6 and 21) would be Leg 1 and Leg 2. By using the pythagorean theorem to see if it is a right triangle you take leg 1 and square it and add it to leg 2 squared (6²+21²) then find the square root of that ([tex]\sqrt{6^2+21^2}[/tex] which equals about 22. So no because in order for it to be a right triangle 22 would need to be 23.
