# Web Sketchpad

### Basic Geometry Tools

All the tools you need to create geometric wonders!

Plus you can change the colours of the objects... and hide them.

### Motion on Grid

This time you will be describing different ways you can move on a grid.

What do you notice? What do you wonder?

### Squares

Use the tools to create a square. Can you make squares within squares? Squares beside squares? See the square designs we created.

### Quadrilaterals

Drag the vertices to create different quads. Is it possible to make a square that is not also a rectangle? A diamond that is not also a parallelogram? Why?

### Broken Symmetry

Help! I'm not symmetrical... and I want to be. Can you see the line of symmetry? Can you drag the squares so that I'm symmetrical across it?

### Discrete Symmetry

Try moving the squares. What happens? Why?

Try to create the images you see to the right of the sketch.

Which images can you make? Why?

Which ones can't you? Why not?
