in chapter 9 section 1 we are learning about right triangles.



when work on right triangles you use SOHCAHTOA

which means sin equals opposite over hypotenuse and cosine is the opposite of sine

cosine equals adjacent over hypotenuse and secine is the inverse of cosine

tangent equals opposite over adjacent and cotangent is the inverse tangent



Hints: SOHCAHTOA can only be use with right triangles


hypotenuse is opposite the 90 degree angle.

example

when doing a problem you have solve for every side of the triangle

you must draw the triangle so that you dont get confused

and you should use parts of the triangle that you had to start off with.
