Discovering Trigonometry

Match the trigonometric ratios

In relation to the defined angle, label the opposite (O), Hypotenuse (H) and Adjacent (A) Angles

Find the sin ratio for this triangle.

Find the cos ratio for this triangle.

Find the tan ratio for this triangle.

Which is the only trigonometric ratio that can equal more than 1?

For any angle, cosθ will always lie in the range ​ (a)   $$<$$ cosθ $$<$$ ​ (b)  

For any angle, sinθ will always lie in the range ​ (a)   $$<$$ sinθ $$<$$ ​ (b)  

Which is equivalent to cos(70)

Using a unit circle, hypothesise another angle $$\theta$$ , where $$\sin\theta$$ will be equal to $$\sin\left(50\right)$$
