1.-Use the Nippe Descartes
window to form the first 15 regular polygons changing the numbers of
sides each time.
| Use
the coloured arrows to the right of Number of
Sides to
change the number. You can also write the number of sides
directly into the box. |
| The Init button restores the
initial values. |
2.- Notice how the more
sides the polygon has the more it looks like a circle.
3.-
Draw a 50-sided polygon and note that the shape is not exactly the
same as a circle.
| Increase
the scale to 160, using the zoom, and move along the axis
(change O.X to -700) to find the edge of the shape. |
