square of longest side ≠ the sum of the squares of the other two sides
It's not a right triangle
Step-by-step explanation:
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
square of longest side: 12 12² = 144
the sum of the squares of the other two sides: 8² + 10² = 164
It's a nonlinear because the x and y values are not increasing at the same ratio each time. This would be an example of a linear function: x l 1 2 3 4 5 6 y l 3 6 9 12 15 18
As x increases by 1, y increases by a multiple of 3
