Download these worksheets to sharpen your geometry skills. Sheets focus on angles, coordinate geometry, triangles, quadrilaterals, transformations, and three-dimensional geometry, and more.

In this interactive activity from ChemThink, students will learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.

This task challenges a student to demonstrate understanding of the attributes of two-dimensional shapes.

Geometry is the study of how to use math to describe and investigate different points, lines and shapes. The way that a shape is described in geometry is with a formula, which is simply a mathematical way to calculate different...

A comprehensive guide for learning all about plane shapes with definitions, properties, types, solved examples, and practice questions.

Explore the world of solid shapes in this mini-lesson. Provides a definition, interactive examples, and interesting practice questions that help with understanding.

Introduces the concept of 3D shapes by learning the definition, types, properties, and three dimensions. Check-out the solved examples for better understanding and try your hand at solving a few interactive questions at the end of the page.

Mathematicians in ancient Greece were amazed by mathematical patterns, and wanted to explore and explain them. They began to study mathematics just "for fun" without a specific application in mind. One of these mathematicians, Thales of...

This chemistry class printout details the main points of molecular geometry and explains bond hybridization and bond angles.

[Free Registration/Login may be required to access all resource tools.] Transformations move and modify geometric shapes. There are several types of transformations that all transform figures in different ways. These transformations can...

Provides a list of area and perimeter formulas for two-dimensional shapes and volume and surface area formulas for three-dimensional solids.

First graders begin to learn about plane shapes in Kindergarten. This lesson plan will serve as review of plane shapes' characteristics and extend into practice in categorizing shapes by defining attributes.

I love blending art and math. I want my students to develop a depth of knowledge for 2D plane shapes and distinguish polygon from non-polygon shapes.

Explore reflection symmetry in some different shapes.

Solve two challenging problems that apply properties of tangents to find the perimeter of a circumscribing shape.

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

Understand the rigid transformation of a rotation.
