Constructing An Octagon |
|
||||
Open your compasses to a radius of half the diagonal of the square and construct an arc with centre one vertex of the square - mark the two points where the arc crosses the sides.
Do that for all 4 vertices of the square giving 8 points which are the vertices of an octagon.
Is the octagon regular?
Can you prove it?
