Use geometer's sketchpad to make curved designs using line segments.
The figure below is a star shaped design. It appears to contain curves. However, it is made up entirely of line segments.
To begin the star design, make a 60 degree angle. Mark eight equally spaced points on each ray. Label the points A through H as shown below. Now connect each pair of points that have the same letter.

To make a complete star, make the same design in six 60 degree angles that have a common central vertex.
1. Make a complete star like the one shown in the first figure above.

The logo for Stephens County High School is a diamond SC.
2. Make a diamond design.
3. Make your own design. You may use several angles and the angles may overlap.
