What are the 3 basic trig functions?

• Sine, cosine, and cotangent

• Sine, cotangent, and cosecant

• Sine, cosine, and tangent

• Cosecant, cosine, and cotangent

How do sine, cosine, and tangent tell us about an angle?

• They describe the angle measure in terms of the ratio of its corresponding sides

• They tell us its measure in relationship to the other angles in the triangle

• We can only use them if we know all side lengths

• They describe the angle measure in terms of the product of its corresponding sides

If I wanted to find the sine of an angle, what side lengths would I need to know?

• base, hypotenuse

• hypotenuse, adjacent

• opposite, hypotenuse

• adjacent, opposite

The cosine of an angle can be calculated by which expression?

• $\frac{hypotenuse}{adjacent}$

• $\frac{opposite}{adjacent}$

• $\frac{adjacent}{hypotenuse}$

• $\frac{adjacent}{opposite}$
