An n-sided regular polygon is inscribed in a similar regular polygon.
You can choose the number of sides [from 3 to 12] using the slider.
You can vary the inscribed polygon by dragging the GOLD dot.
As a function of the number of sides and the position of the GOLD dot -
- what fraction of the area of the Blue polygon is covered by the Green polygon?
- what is the ratio of the perimeters of the two polygons?
What other questions [could,would] you ask?
