Quadrantal Angles

In this angle worksheet, students identify angles and then determine the related angle. Examples are provided. This one-page worksheet contains 36 problems, with answers at the bottom of the page.

In this trigonometric functions activity, 11th graders solve and complete 19 various types of problems. First, they find the exact value of the six trig functions of the terminal side in standard position contains the given point. Then,...

Here's an algebra II activity that strives to make the concept of a radian less abstract and more conceptual. It takes a hands-on approach to exploring the idea of a radian and allows individuals to develop a definition of a radian...

In this trigonometry worksheet, students convert between degrees and radians. They use the unit circle to identify the measure of angles. There are 28 questions with an answer key.

Students identify positive and negative angles using the Unit Circle. For this pre-calculus lesson, students identify the different angles on a unit circle using the coordinate plane and the four different quadrants as a guide. They...

Calculate exact trigonometric values using the angles of special right triangles. Beginning with a review of the unit circle and trigonometric functions, class members use their knowledge of special right triangles to find the value of...

It's all about the patterns! Young scholars learn that the unit circle repeats itself in all four quadrants. Using these patterns, they evaluate the sine, cosine, and tangent of special angles.

Students play a SMART Board Jeopardy game. They examine the angle measure given a trig function of an angle. Students explore quadrants, degree and radian measure. They evaluate trig expressions.

Learn how to measure the reference angles in degrees and radians.  Students find reference angles that are coterminal with a given angle.

In this Unit Circle instructional activity, learners explore a method to help remember the coordinates of the points in the first quadrant on the unit circle.  Answers are provided as well as a completed unit circle.
