Learning how to use GeoGebra for Constructions.

Geometric Constructions using a compass and a straightedge.

1. Place three non-collinear points on your screen. 2. Turn the labels on so that you can see the names of the points. 3. Draw ray AB, and ray AC. 4. Place your compass at point A so that it passes through point C and the arc intersects ray BC. 5. Use the intersect feature to create the intersection point. 6. Turn the labels on for all the intersection points. 7. Place your compass at another point on the figure to draw another circle. 8. Create and label all the new intersection points.
