We are going to draw polygons using two diferent methods. The first one is knowing the inscribed circunference of the poligon.
Now see the video for each drawing and draw them in your notebook, you also have the drawings in the book with explanations pages and

Geometric construction of regular inscribed polygons. General method.
This is the method we use to draw any regular polygon inscribed in a circle, or divide the circumference into any number of equal parts. We are going to divide our polygon in 10 equal parts, remember to use parallel lines to apply the Thales Theorem as we learnt last year.
