A Apothem
If it's a regular polygon, and you know the length of the perpendicular from the center to the middle of a side, and the length of a side, A = LNS, where L is the length of the perpendicular, N is the number of sides, and S is the number of sides. See the link for a more detailed explanation of various ways to compute the area of regular polygons.
Correct.
It is an apothem line that connects the center of a polygon to the center of an outer side.
That is called the apothem. The definition is: An Apothem is the distance from the center of a regular polygon to the midpoint of a side

No, it is the distance from the center of the polygon to the centre of one of its sides.
Apothem!
The line drawn from the center of a regular polygon and perpendicular to a side.
A Apothem
You can find the intersection of the angle bisectors or the intersection of the perpendicular bisectors of each side.
the radius
A regular polygon has a center, much as a circle does. There are also the sides which are all the same lengths. Then there is the apothem which is any segment that goes from the center and is perpendicular to one of the polygon's side. Then angles are also parts and they are all the same. You might consider the perimeter a part and of course it is the sum of the sides.
