This triangle is not a right triangle: 1562 +602 + 1442
This triangle is not a right triangle: 1562 +1442 602
This triangle is a right triangle: 602 + 1562 – 1442
This triangle is a right triangle: 602+1442 – 1562
Which best explains why this triangle is or is not a right triangle

D) This triangle is a right triangle: 60^2+144^2 - 156^2 = 0

This is the same as saying 60^2 + 144^2 = 156^2

You would use the pythagorean theorem. In this case, a = 60, b = 144 and c = 156. The longest side is always the value of c. The order for the values of 'a' and 'b' do not matter. Convention usually has 'a' being the smaller of the two.
