No,this is not a right triangle

Work Step by Step

You have to use the Pythagorean theorem to determine if this is a right triangle. (A=8, B=40, C=41): $a^{2}$+$b^{2}$=$c^{2}$ $8^{2}$+$40^{2}$=$41^{2}$ -simplify the exponents- 64+1600=1681-simplify like terms- 1664=1681 They are not equal so this is not a right triangle. It is an obtuse triangle.
