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

This study guide on angles covers key vocabulary, ways to name angles, how to measure them, the Protractor Postulate and the Angle Addition Postulate, types of angles, congruent angles, angle bisectors, and angle pairs. It is available...

In this interactive website, students practice various math skills such as identifying different types of angles, use the degree symbol, estimate and measure angles, and construct angles.

In this lesson, students learn about four types of angles: adjacent, vertical, supplementary, and complementary. They explore the relationships between these types of angles by folding paper, measuring angles with a protractor, and...

Step-by-step instructions accompanied by illustrations that demonstrate how to use a protractor to draw angles and to measure angles.

In this lesson, middle schoolers learn more about the characteristics of parallelograms by folding paper and measuring the angles in a parallelogram. Students use a ruler and protractor to draw parallelograms with given properties. Then,...
