## Algebra 1: Common Core (15th Edition)

You have to use the Pythagorean theorem to determine if this is a right triangle. A=6, B=24, C=25: $a^{2}$+$b^{2}$=$c^{2}$ $6^{2}$+$24^{2}$=$25^{2}$ -simplify the exponents- 36+576=625-simplify like terms- 612=625 They are not equal so this is not a right triangle.
