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 poster on a bulletin board in my classroom with several other 11 x 17 posters I created. I shared my pythagorean theorem poster with you the other day.

As I continue to transfer files to my own blog domain, you will likely see several of these other posters popping up in posts since it seems like I never really blogged about them after I created them.
