Students are challenged to identify and measure angles created by parallel lines and a transversal as well as complementary and supplementary pairs.

This geometry lesson and video explain angle measure, how to measure angles with a protractor, and has varied exercises for the students.

On this interactive website students practice various math skills using a real life scenario. Those skills include finding angles, drawing angles larger or smaller than a given angle, and locating right angles.

Find an angle's measure when given the measures of its parts. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Here is a site that clearly and thoroughly explains many topics regarding measurement of angles, including standard position, degree measure, and coterminal angles. There are example problems solved, problems for the student to attempt,...

This task challenges a student to demonstrate understanding of the concept of measurement.

This lesson plan provides students with an opportunity to practice drawing and measuring triangles and angles. It also shows pictures and gives definitions of each type of angle and triangle.

Explains what "tangent" is and its role in the right triangle. Slope of a line is investigated and tangent for special common angles is given. Angle of elevation and angle of depression are also covered here.

Convert angle measures given in degrees to radians and vice versa.

This site offers a discussion on radian measure. The site offers pictures and explanations to clarify the formulas given. (Note: The free download at the end of the page will not work in archived version of site.)

In this lesson students will practice finding the area rectangular shapes and irregular shapes with right angles and understand why the area formula works for rectangular shapes.

In this lesson, students learn to classify triangles by the size of the angles and the measures of the sides. Students will use interactives to explore equilateral, isosceles, scalene, acute, obtuse, and right triangles. Included are...

Explore and measure a variety of quadrilaterals.

Learn about arcs with this handy reference guide. Provides a detailed definition, examples, and an interactive activity that enhances further explanation. Includes links to related topics.

Learn how the Law of Cosines uses the measure of angle C to provide an equation that relates the three sides of the triangle with angle C.

Young scholars measure the angles of refraction of laser light traveling through gelatin, then plot their data to calculate the gelatin's index of refraction.
