Answer with explanation:
An "apothem" is a line segment from center of that polygon to any of the sides ,such that that line segment is perpendicular to the side on which it is drawn.
For, the following Polygons
To find find the Center of the Polygon.
We will draw these Regular polygons inside the circle such that, the vertices of these polygons cut the circles , in such a way that, each side is the chord of the circle.
The Theorem Which states relation between center of the circle and chord is , line drawn from the center of the chord ,which is perpendicular to chord passes through center of the circle.And any two perpendiculars which are drawn from the center of the chord meets at the center of the circle.
In all the cases we have used the Special triangle = Isosceles triangle, and the property of chord to find the center of the each polygon which is center of the circle also.
→None of these
