There are three main trigonometric ratios of sides of a right angle triangle.[br][br]The ratios are sine, cosine, and tangent
[math]Tangent=\frac{opposite}{adjacent}[/math]
[math]sine=\frac{opposite}{hypotenuse}[/math]
[math]Cosine=\frac{opposite}{adjacent}[/math]
What trigonometric ratio can you use for the triangle above
Why does changing the angle value change the length of the hypotenuse and opposite side?
What happens when the angle gets closer to 0 and 90 degrees?
