Tangents, Sine and Cosine with Right Triangles

Sine is ​ (a)   over ​ (b)   and ​ (c)   is opposite over ​ (d)   , which ​ (e)   is adjacent over hypotenuse.

• opposite

• hypotenuse

• tangent

• adjacent

• cosine

• sine

• length

Find the ratio of sin C. Use \sin\theta=\frac{O}{H}

What is the ratio for tangent?

• O/A

• A/O

• A/H

• O/H

Tangents are...

• Unrelated rants that occur in the middle of a normal conversation.

• the ratios of the sides (other than the hypotenuse) opposite and adjacent to an angle in a right triangle.

• the longest side of a right triangle.

• ratios of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
