Activity overview:
We will investigate a regular polygon with 3 sides (an equilateral triangle), its center, a vertex of the polygon, and the apothem. Remember, that we are discovering a formula for the area of a regular polygon in terms of the number of sides n and the length of a side s. 5.

The point of intersection of the axes of symmetry, point , is the geometrical center of this contour as well as the center of equilateral triangle . Considering the theoretical contour as a heavy thread, the point , the geometrical center of this thread, can be calculated as the center of mass of this thread.
