Answer:
Explanation:
sqrt(169) = ±13
13*13 = 169
(-13)*(-13) = 169
Proving the converse of the Pythagorean theorem means proving that if the sum of the squares of the lengths of the shorter sides of a triangle equals the square of the length of the longest side, then the triangle is a right triangle
a^2 + b^2 = c^2
This is the Pythagorean theorem
a and b are the shorter sides and c is the longer side
