5.7 The Pythagorean Theorem
Pythagorean Theorem - a^2 + b^2 = c^2
Theorem 5-7-1 Converse of Pythagorean Theorem - If the sum of the squares of the
lengths of 2 sides of a triangle is = to the square of the length of the 3rd
side, then the triangle is a right triangle.
Theorem 5-7-2 Pythagorean Inequalities Theorem - If
c^2 > a^2 + b^2, then triangle ABC is an OBTUSE triangle; If c^2 < a^2 + b^2, then
triangle ABC is an ACUTE triangle.
