Teach your students to sort triangles as acute, right, or obtuse based on their internal angle type.

Fifth graders review types of angles, triangles, and polygons in this handy geometry review.

Children find the unknown angles for five triangles, then identify whether the triangle is right, acute, or obtuse, in this geometry worksheet.

Strengthen your child's geometry skills with this printable worksheet. Use this resource with your students to classify two-dimensional shapes like parallelograms, quadrilaterals, squares, and triangles.

Use this resource to help your students develop their understanding of trapezoids and other two-dimensional shapes. Students will compare the attributes of trapezoids to those of other plane figures, such as triangles and ovals, in this geometry activity.

Give your students a chance to sort polygons into categories that make sense to them.

Assess your students’ knowledge of geometry concepts from polygons to coordinate planes!

Assess kids' understanding of geometry with this sheet.

In this worksheet, learners will find and draw a line of symmetry on nine shapes.
