Identifying Unit Circle Angles

Mark $$\frac{\pi}{2}$$ radians on the unit circle.

Given the point (-1,0), which radian value are you at on your Unit Circle?

The graph shows the unit circle with angles $$x$$ and $$\pi-x$$ .

What is the exact measure, in radians, of angle $$\pi-x$$ ? Write your answer in terms of .

In which quadrant is 300° (a)  

Identify the Positive angle in both radians and degrees that represent point I.

Using θ as a reference angle, mark the triangle sides as Opp, Adj, and Hyp. Label these on the triangle on your paper.

In which quadrant is 150° ?

Identify the Positive angle in both radians and degrees that represent point D.

An angle terminates in the 2nd quadrant and $$\cos\theta=-.35$$ . What is $$\sin\theta$$ (round to the nearest hundredth)?
