On these activities we are going to do rotations without the rotation tool.
To rotate point A about a center point B
Steps
1. Make a circle with center B and radius BA.
2. Draw in line segment AB
3. Use the angle with given size tool. Click on A first , B (center) second, then type in the rotation magnitude (degrees) and direction (clockwise or counterclockwise).
4. The image of A will be where the circle intersects the new side of the angle. I believe geogebra will give you that point and call it A'. Draw in the segment from B (the center) to A'
Now go ahead and repeat the process rotating C about point D.
