Converse of Pythagorean Thm
If the square of one side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
Some Pythagorean Triples…
3,4,5 (or 6,8,10 or 9,12,15 or 12,16,20, or 15, 20, 25)
5,12,13 (or 10, 24, 26) 8,15,17 7,24,25
Other options…
If c^2<a^2+b^2, then m<C is less than 90… and
triangle is ACUTE
If c^2>a^2+b^2, then m<C is greater than 90… and
triangle is OBTUSE
