Determining whether three given side lengths will form a right triangle.
Do the lengths of the three sides of the triangle to the right in fact form a Right Triangle? Using the Pythagorean Theorem we can substitute in a, b and c and see if |
5^2 + 12^2 = 13^2
25 + 144 = 169 169 = 169 Yes! If a^2 + b^2 = c^2 then you have a Right Triangle. So the above triangle is a right triangle because the left side is equal to the right side. |
