Express the length a, b, c, and d in the figure in terms of the trigonometric ratios of θ. Problem
Express the length a, b, c, and d in the figure in terms of the trigonometric ratios of $θ$. (See the image below)

Progress
I can figure out $c$ usng the pythagorean theorem. $a^2+b^2=c^2$ which would be $2$. Is that correct? How do I solve the rest?

Compute $\sin(\theta)$, $\cos(\theta)$ and $\tan(\theta)$ using your picture. What do you see?
