Trig Ratios

If you are given the opposite side and hypotenuse, which trig function should you use?

• sine
• cosine
• tangent
• cotangent

If you are given the two sides that are not the hypotenuse, which trig function should you use?

• sine
• cosine
• tangent
• cotangent

If you are given 2 of the sides to an obtuse triangle, which trig function should you use to find the other side?

• sine
• cosine
• tangent
• You can only use trig functions on right triangles.

If you are given the hypotenuse and an adjacent side, which trig function should you use?
