A triangle has sides of 6 m 8 m and 11 m is it a right-angled triangle?​

No

Step-by-step explanation:

If we use the Pythagorean theorem, we can find if it is a right triangle. To do that, set up an equation.

If the triangle is a right triangle, c would equal 11

Solve.

Then find the square root of 100.

The square root of 100 is 10, not 11.

So this is not a right triangle.

I hope this helps!
