## SOH CAH TOA Notes

I created these SOH CAH TOA notes for my Pre-Calculus students a few years ago to review how to find the trigonometric functions of an angle, given a triangle. First, we reviewed the different parts of a right triangle. I have also created a poster of the parts of a right triangle that might be …

## Trig Functions Posters

I created these trig functions posters a few years ago when I was teaching a year-long trigonometry course. Somehow, they never got a blog post of their own. I created separate posters for the three basic trig functions and the three reciprocal trig functions. I designed these posters to print on 11 x 17 cardstock. …

## Parts of a Right Triangle Poster

I created this Parts of a Right Triangle poster several years ago when I was teaching trigonometry. I wanted to emphasize the vocabulary words for adjacent, opposite, and hypotenuse before we jumped into right triangle trig. I designed this parts of a right triangle poster to print on 11 x 17 cardstock. I hung this …

## Clinometer Activity and Foldable

I love this clinometer activity for giving my trigonometry students extra practice finding missing angles and sides of right triangles. Plus, it answers the question of “When will we ever use this?” I printed a clinometer template off of VirtualMaths.org for them to use. I mistakenly assumed that they would be able to put together …

## Finding Missing Angles of Right Triangles Practice Book

I created this finding missing angles of right triangles practice book for my trigonometry students to glue in their interactive notebooks. My students were a bit miffed that they had to just write these equations.  They thought I should have given them a foldable for these! I did make them a practice book, though.  These …
