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.

A comprehensive guide for learning all about concave shapes with definitions, the difference between concave and convex, examples, and practice questions.

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.

Describing 3D shapes in Pre-K and Kindergarten is now an expectation as it is a key geometry standard. This resource contains 3D shapes activities and resources for practicing this standard. Included are chants, videos, games, poetry,...

[Free Registration/Login may be required to access all resource tools.] Provides a brief overview of the different types of symmetry and of how to tessellate a shape.

This is one of my favorite Open House activities. We use our shapes to create "mystery" glyphs that are hung in the hallway. Families use the legend to guess their child's glyph!

Use quadrilateral properties that are unique to parallelograms to prove that the given shape is a parallelogram.

Explore reflection symmetry in some different shapes.

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.

In this activity, students will learn that math is important in navigation and engineering. Ancient land and sea navigators started with the most basic of navigation equations (Speed x Time = Distance). Today, navigational satellites use...
