Quadrantal Angles

In this angle measurement worksheet, students identify the domain and range of given problems.  They determine the amplitude, period and horizontal translation of given functions.  This two-page worksheet contains 16 problems.

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...

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...

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 angle activity, students solve ten multiple choice and six free response questions.  These precalculus questions cover angles, radians, and right triangles.

For this unit circle instructional activity, high schoolers answer 90 short answer questions about the unit circle.  Students sketch angles given a radian measure.  High schoolers find the trigonometric values of various angles on the...

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 worksheet, students 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.
