Elementary schoolers find the missing angle in a complementary angle.  This two-page instructional activity contains six problems. Answers are provided.

Is it a line, line segment, ray, or angle? Identifying geometric figures is the focus. In addition to identification, learners recognize right angles or tell if an angle is less than or greater than a right angle. They tell if lines are...

Upper graders solve ten multiple choice problems about angles and measuring angles.

In this recognizing geometric figures worksheet, students read descriptions, draw, label, and write the names and symbols for basic geometric figures. Students solve thirteen problems.

Over the course of 18 problems, learners identify angles as complementary, supplementary, vertical or adjacent. They name relationships in angles such as alternate interior, corresponding, and alternate exterior angles. They apply the...

Explore types of angles and the characteristics of each. After observing a PowerPoint Presentation, learners tour the school facilities and use a digital camera to capture prescribed angles. Using the digital pictures and written...

In this triangles worksheet, 10th graders solve and complete 10 different problems that include applying the Triangle Inequality Theorem. First, they use the illustrated triangles and the data table to test the theorem. Then, students...

Students examine the painting, "Sunflowers," by Vincent van Gogh noting the use of the yellow color, the wiggly lines, and the "globs" of paint used to create the picture. Pictures are painted using van Gogh's image as a model.

What's a trigonometric ratio? It is a ratio between two sides of a right triangle. In this problem, find cosine(A) in the given right triangle. Use the ratio of the adjacent side divided by the hypotenuse to find cos(A). The instructor...

Oh no, there is a missing angle in a quadrilateral. Where did it go? It didn't go anywhere, it's just missing the value of the angle. So how do you find that missing value? Use a formula of course. Everything in algebra uses a formula....
