In this trigonometry learning exercise, students solve for trigonometric functions. They convert between radians and angles using the properties of sine, cosine and tangent. There are 30 problems on this handout.

In this online, interactive worksheet (7), students complete ten problems in 12 minutes to help prepare then to take the SATs. The problems vary in difficulty and content.

In this Pythagoras' Theorem worksheet, students solve problems having to do with square roots and numbers to a certain power. Students match up the answers for 30 problems.

Middle schoolers engage in a activity that is concerned with the concept of similarity. This takes higher order thinking skills and being able to separate into categories. Specifically in this activity they are introduced to the scale...

In this distance worksheet, learners calculate the lengths of sides and diagonals of figures.  Students also compute lengths in shadow problems.  The solutions are provided by clicking on the "show answers" tab at the bottom of...

In this angle activity, students answer forty mental math questions divided into four problem sets.  These problems require students to remember angle facts and so simple calculations mentally.

In this geometry activity worksheet, students cut a 6x6 according to the directions and construct the 4 listed shapes from the pieces. Students also respond to 5 questions that require them record details regarding the 5 listed shapes.

In this geometry skills instructional activity, students follow the provided instructions to cut out geometric shapes on the instructional activity and build 5 shapes out of the pieces. Students also complete a graphic organizer...

In this trigonometry activity, students solve and complete 5 various types of problems. First, they find the exact ratios for each trigonometric function. Then, students use the expansion to find the exact value of a given trig function....

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Students explore tessellations. They are shown a selection of shapes. Students identify shapes that tessellate and justify their answer. Students create their own tessellation.

Learners observe a selection of shapes. They identify which shapes will tessellate and justify their answer. Students apply the symmetry and angle properties of polygons to create tessellations.

Explore and learn about the features and properties of a right triangle in this lesson. Includes examples and practice questions.

Students learn how to find a side in a right triangle. The tutorial consists of notes, examples, and practice problems to check for comprehension.

Students learn how to find an angle of a right triangle. The tutorial consists of notes, examples, and practice problems to check for comprehension.

The resource investigates right triangle. Topics explored are isosceles, scalene, and 3,4,5 triangles. Examples, illustrations, and definitions are included.

[Free Registration/Login may be required to access all resource tools.] Different types of right triangles and trigonometric ratios for special right triangles are covered in this study guide.

Pythagoras' Theorem: In any right-angled triangle, the square of the length of the hypotenuse (the side that lies opposite the right angle) is equal to the sum of the squares of the other two sides. (A+B=C)

Given two sides in a right triangle, find one of the acute angles using trigonometry. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Solve word problems by modeling real-world (and not-so-real) situations as right triangles and using trigonometry. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Use your knowledge of 30-60-90 and 45-45-90 triangles to solve some problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this activity, students explore a right angled triangle and its trigonometric concepts. They investigate the trigonometric ratios for the angles of the triangle.

How can trigonometry be used to find the area of a triangle or parallelogram? Does the triangle need to be a right triangle, and how accurate can the results possibly be? The answers to these questions are found here along with several...

A good introduction to trigonometric identities, equations that are always true for a right triangle and require knowledge of the functions sine, cosine, and tangent.
