Question

The lengths of a triangle are 6,8,and10 can the triangle be a right triangle?

Answer 1

Check it using pythagoras theorem:
\[c^2 = a^2+b^2\] where c is the hypotenuse (longest side)

Check that
\[10^2 = 6^2 + 8^2\]

Answer 2

If it satisfies that criteria, then it must be a right triangle.
