Pythagorean theorem using side lengths chosen from 6 cm, 9 cm, 12 cm, and 15 cm. I cant tell which one it is. 1. Knowing that 9^2+12^2=15^2 draw any two of the sides with a right angle between them. The third slide will fit to form a right triangle.
2. Knowing that 9^2 + 12^2 =15^2, draw the 9 cm side and the 12 cm side with a right angle between them. The cm side will fit to form a right triangle
