A key characteristic of trapezoids is that they have a set of parallel lines—lines that never intersect. Use this helpful geometry resource with your students to practice identifying parallel lines in trapezoids and comparing different 2-D shapes.

It’s time to flex your math muscles with this great geometry activity! Use this resource with your students as they practice identifying and counting angles in different two-dimensional shapes.

In geometry, an angle is formed when two lines meet. Use this resource with your students to enhance their understanding of angles in polygons. Students will seek to identify and differentiate between right angles and other angles across various shapes.

Angles come in all kinds of shapes and sizes—can you spot them all? Use this resource with your students to practice finding all the angles in 2-D shapes. Your students will then be challenged to identify right angles in two-dimensional shapes.
