# Introduction to Geogebra (Transformations)

## Explore 1: Translations

- Draw a Triangle using “Rigid Polygon.” Make this grey.
- Draw a vector that will translate figures down and to the left.
- Draw another vector that will translate figures horizontally.
- Translate the original triangle using the first vector. Make this green.
- Translate the original triangle using the second vector. Make this blue.
- Choose someone in class. Bring your file over to them. Show them and ask them to identify and describe to you what you did.

## Explore 2: Reflections

- Draw a Quadrilateral (4 sides) using “Rigid Polygon.” Make this grey.
- Draw a vertical line.
- Reflect the figure over the line.

- Draw a pentagon (five sides) using “Rigid Polygon.” Make this blue.
- Draw a horizontal line.
- Reflect the figure over the line.

- Draw a third figure using “Rigid Polygon.” Make this red.
- Draw a line with a positive slope.
- Reflect the figure over the line.
- Choose someone else in class. Bring your file over to them. Show them and ask them to identify and describe to you what you did.

## Explore 3: Rotations

- Draw a pentagon using “Rigid Polygon.” Make this purple.
- Draw a point.
- Rotate the figure 90 degrees CCW about that point.
- Rotate the figure 74 degrees CW about that point.
- Choose someone else in class. Bring your file over to them. Show them and ask them to identify and describe to you what you did.
