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 = 15
Hence greatest angle will be opposite 15
Let us check pythagorean theorem
smaller sides are 9 and 12
Square and add them
9 square +12 square = 81+144 = 225 =15 square
We find that Pythagorus theorem is satisfied
Hence it is concluded that the triangle is right angled and Ariel was wrong
