Discovering Trig Ratios

Look at the ratio of sides in the right triangle below.

[br]Opposite= The side across from angle β[br][br]Adjacent= The side next to angle β[br][br]Hypotenuse= The side across from the right angle[br][br]-These three sides can be divided in what we call [i]Trigonometric Ratios[/i].[br][br][b]Instructions:[/b] Move the angle slider below the triangle and point B to create different triangles. View the ratios beside the triangle. When do they change? When do they stay the same?

Do the ratios change when the angle changes? What about when the side lengths change?

Select the true statements:

The ratios change when the angles change. The ratios remain the same for every angle. The ratios stay the same for any single specific angle. The ratios change when the sides change.
