Before we study trigonometry, we need to know how the sides of a right triangle are named. The three sides are called hypotenuse, adjacent and opposite sides. In the following right triangle PQR, the side PQ, which is opposite to the right angle is called the hypotenuse. (The hypotenuse is the longest side of the right triangle.) the side RQ is called the adjacent side of angle q . the side PR is called the opposite side of angle q .

Technical Notes

Students will need Calculators.If they don't have one, I will given them one to use.


Studnets need to know what a Right Triangle is.

Learning Objectives

Students will be able to use the calculator to the side or an angle of a right triangle using Sin, Cos, or Tan.


Homework will be to go to regentsprep.org and do some problems. Also students will be asked to use the calculator to find the angle 1. Tan 45, 2. Sin 23, 3. Cos 12, 4. Tan 67, & 5. Sin 78
