G.SRT.6 Trig ratios

This applet is designed to help you discover the right triangle trig ratios. You will need to know the opposite, hypotenuse, and adjacent sides of the triangle with respect to a given angle. Keep B a 90 degree angle. Move the other points and pay attention to the AH,OH,OA, and sin(a),cos(a), tan(a). If you move the points so that B is not 90 degrees, what do you notice?
