A triangle has sides of 8cm , 19.2cm, and 20.8 cm. is it right angled?

please explain :D

The triangle is a right angle triangle.

Step-by-step explanation:

Given,

The lengths of the triangle are 8 cm, 19.2 cm and 20.8 cm.

To find whether the triangle is right angled.

Formula

By Pythagoras theorem we know that if any triangle satisfies the condition

hypotenuse² = base²+ perpendicular² there triangle will be right angled.

Now,

8²+19.2² = 64+368.64

              = 432.64

              = (20.8)²

It satisfies the Pythagoras theorem.

Hence it is a right angle triangle.

no he doesnt because "-16' is negatiive
