Question

Construct a regular heptagon

Answer 1

are you asking how to construct one?

Answer 2

Yes

Answer 3

if you use a protractor it is easy (central angle of each side is 51.43 deg

I think it is not possible with ruler and compass

Answer 4

https://en.wikipedia.org/wiki/Constructible_polygon

this page confirms that it is nor possible

Answer 5

it is possible. But you need to do it like this.
1) Find the central angle (this is just 360/number of sides)
2) Use a protactor and outline these angles from the centre.
3) Draw and circle and have those angles connect with the circle
4) Join the points

Answer 6

So you want to find the central angle (i.e. the size of each angle cut by the spokes that will form the edges of the polygon), then measure them out from a circle centre and join the pts
