Identifying Sides of Right Triangles
- Tim Brzezinski
The applet below provides an introduction as to how we label the legs of a right triangle with respect to ONE of its acute angles. (Notice angle A, B, A', and B' are acute angles of a right triangle.) The triangles shown below are similar triangles. Can you explain why?
1) How would you describe the hypotenuse of a right triangle? What is it? How do you easily find it? 2) How, within a right triangle, would you be able to identify an acute angle's OPPOSITE LEG? 3) How, within a right triangle, would you be able to identify an acute angle's ADJACENT LEG?
