**Trigonometry:**

Trigonometry is a branch of mathematics that studies relationships involving lengths and angles of triangles.

**Trigonometry:**

Most of the time we will be working with right triangles. The first thing to remember when using right triangles is the Pythagorean Theorem. Below are the guided notes for this section. This information will be given and discussed in class.

**Pythagorean Homework is below.**For each problem, sketch a picture, label it appropriately, develop an equation, and solve. Be sure you answer the question that is being asked.

In case you might have missed some of the information in class, the guided notes "answers" are given below.

The second section of Trigonometry deals with two particular types of right triangles called 'special triangles.' These are right triangles that have angle measures of 30, 60, and 90 degrees and 45, 45, and 90 degrees. What makes them special is that the ratio of the lengths of their sides is constant, that is always the same. Note sheet for this section is below. Again, this information will be reviewed and practiced in class.
