# Revisting Pythagoras Theorem

## About the activity:

This activity is designed for introductory workshop on integration of GeoGebra with Google Classroom. Participants will experience use of GeoGebra worksheet to interact with and explore Pythagoras Theorem.

## Visual Proof of Pythagoras Theorem:Drag the points and match the colours, what do you notice?

**Share your observation: what do you notice? What does this prove?**

There are many visual proofs of Pythagoras Theorem , following applet will verify the theorem. Get started by the first checkbox -squares on sides

## Verification of Pythagoras Theorem

The sum of areas of squares drawn on the legs of right triangle equals the area of the square on the hypotenuse of the triangle.

## Q2:

Which of the following **cannot** be the lengths of the sides of a right triangle?
