Explain how the three trig functions can be found by creating a ratio of the side lengths in a right triangle? what are the three trig functions? how can they be written as a ratio of the sides?

Three trigonometric functions are sinФ, cosФ, tanФ

For the shown right triangle ABC, AB is side opposite to angle Ф, BC is side adjacent to angle Ф and side AC is hypotenuse side( side opposite right angle)

All three trigonometioc ratios can be found from sides of triangle by

formulas as written

SinФ =

cosФ =

tanФ =
