The Next Generation of Geometry is here! Learn more.
The Desmos Geometry Tool is a dynamic, interactive workspace that allows for explorations in measurement, construction, transformations and more! Start with the video to the right, then get in shape with the tips below!
Use the Select tool to select an object you create in the workspace. You can choose to label measurements based on the type of object. You can measure the length of segments, area and perimeter of polygons, or degrees of an angle.
Use this measurement feature to help students see patterns and discover relationships in Geometry!
Measurements are dynamic and adjust themselves as the shapes change. Students can discover further relationships with this type of interactivity.
Use More Tools to access our Constructions menu. Choose a compass, create parallel or perpendicular lines, or find midpoints.
Use these construction features and the dynamic nature of the Desmos Geometry Tool to enhance student understanding of traditional compass-and-straightedge constructions.
The dynamic Desmos Geometry workspace can partner with these construction tools to allow students to discover relationships in angle measures.
The Transform menu allows for reflections, translations, rotations, and dilations. Each tool walks you through how to use it once selected!
Show students how a regular hexagon can be constructed using repeated 60-degree rotations of an equilateral triangle.
Scale a figure repeatedly—from a single transformation.
Save and Share Your Work
Click the three horizontal bars in the top left corner to access a menu that lets you sign-in, see all of your saved constructions, and visit examples created by the Desmos faculty!
You can create a new account from this menu, or log in to your existing Desmos account.
Give each saved construction a title, based on the topic, content, or unit of study. Each Desmos Geometry construction has a unique URL that you can copy and share with others!
