Below are a number of worksheets covering trigonometry problems.
Trigonometry, at it's most basic level, is concerned with the measurement of triangles  calculations of unknown lengths and angles. The trigometric functions have a number of practical applications in real life and also help in the solutions of problems in many branches of mathematics.
In trigonometry we study relationships involving lengths and angles of triangles. During the 3rd century BC, the Hellenistic world developed trigonometry to study astronomy. These early astronomers noticed there was a relationship between the angles inside a triangle and the lengths of the sides. They found if they new either some angles or some lengths or a combination of both, then they could calculate the others. From these early astronomy beginnings, trigonometric functions are used in many fields including physics, engineering, acoustics, surveying and acoustics.
High school math students can use these trigonometry problems for study purposes. High School Teachers  you're welcome to copy these worksheets for classroom use. Parents  if you'd like to help your child learn math we suggest you start with our math tutorial section before returning to use these worksheets.

A note about year levels
Where appropriate each worksheet is given a year level that it is applicable
to. As we're all in different countries the year level corresponds to
the number of years at school. So, for example, a worksheet for Year
11 is for students in their 11th year of school.
Worksheets for earlier or later years may still be suitable for you.

TRIGONOMETRY TUTORIALS
 Trigometric Ratios
We can use Pythagoras' Theorem (see above) to calculate the length of an unknown side in a rightangled triangle when we are given information about the lengths of 2 other sides.
However, if we are given information about an angle (other than the 90 degrees) and one side and need to calculate the length of another side then we use the trig ratios.
This first tutorial takes you through naming the sides of a triangle and an introduction to the trig ratios.
This tutorial is suitable for students in Year 10 or 11.  Calculating
sides using the trigometric ratios.
We can use trig ratios to calulate the length of a side on a triangle if we know the length of one side and the size of one angle.

This tutorial is suitable for students in Year 11 or 12.  Calculating
angles using the trigometric ratios.
OK, so probably saw this coming. If you know the length of the two sides of a rightangle triangle then you can caculate the size of the other angles inside the triangle. Nifty huh? We're really getting to know stuff about rightangle triangles.
