Shaylee wanted to know if a triangle whose legs are 15 feet and 8 feet and whose hypotenuse is 17 feet is a right triangle. She put into her calculator 17x17 =289. Then she put into her calculator 15x15 =225 and 8x8 =64, and added 225 and 64 together. Is the triangle a right triangle? Yes, because the square of the hypotenuse is equal to the sum of the squares of the legs of the triangle. No, because 15+8 does not equal 17. No, because there is not enough information to solve this problem. Yes, because 8x15x17 is equal to 2040. None 1 out of 20 Time's upTime is Up!
