Showing Results for properties of triangles

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

This colorful worksheet asks your fourth grade geometry detective to practice identifying right triangles.

Let your fourth grader play triangle detective: can she spot the acute triangles on this worksheet?

Is your fourth grader reluctant to practice geometry? This colorful worksheet, which explores obtuse triangles, may be just what he needs!

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

Challenge your students to identify or draw 18 different geometric shapes, including polygons, quadrilaterals, and triangles.

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

Is your child in need of a geometry review? This worksheet covers the basic 2-D shapes, from circles and triangles to pentagons and hexagons.

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.
