Ariel completed the work below to show that a triangle with side lengths of 9, 15, and 12 does not form a right triangle. mc018-1.jpg Is Ariel’s answer correct? No, Ariel should have added 122 and 1

Answer:Ariel answer is wrong.Step-by-step explanation:Given that Ariel had done a Math problem for a triangle with sides 9,15 and 12.  She concluded that these sides are not that of a right triangle.To check whether Ariel is right:Greater side = 15Hence greatest angle will be opposite 15Let us check pythagorean theoremsmaller sides are 9 and 12Square and add them9 square +12 square = 81+144 = 225 =15 squareWe find that Pythagorus theorem is satisfiedHence it is concluded that the triangle is right angled and Ariel was wrong
