The Geometer's Sketchpad: Dynamic Geometry Software

Explore geometry, algebra, trigonometry, calculus and other areas of math with The Geometer's Sketchpad, an interactive tool for creating dynamic drawings and visualizing mathematical concepts.

What is The Geometer's Sketchpad?

The Geometer's Sketchpad is a popular and widely used dynamic geometry software tool in math education. It was developed to allow students to explore and visualize geometry, algebra, trigonometry, calculus, and other areas of math in an interactive, engaging way.

With Sketchpad, students can create dynamic drawings and manipulate mathematical objects like points, lines, circles, angles, polygons, curves, and functions. As objects are moved or transformed, their mathematical properties and measurements update automatically. This interactivity enables deeper investigation and understanding of core math concepts and relationships.

Some key features of The Geometer's Sketchpad include:

• Interactive geometry constructions with draggable points and dynamic elements
• Built-in tools for creating key geometric figures like triangles, quadrilaterals, circles, polygons, and more
• Measurement tools for lengths, angles, slopes, areas, and more that update as constructions change
• Function graphing tools with adjustable parameters
• Animation and scripting capabilities to demonstrate mathematical concepts
• Compatibility with digital whiteboards and projectors for classroom demonstrations
• Supports explorations and investigations in Euclidean and non-Euclidean geometries
• Useful in a wide range of math courses from middle school through college level
• Available as a standalone desktop software or web/notebook app

With its emphasis on experiential, inquiry-based learning, The Geometer's Sketchpad is an engaging way for students to visualize, explore, and deepen their understanding of key mathematical concepts across many branches of mathematics.
