the highest piont, the top or apex. 2 each angular point of a polygon, polyhydron, or other figure.
a fixed reference line for the measurement of coordinates.
a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center of the polygon that is perpendicular to one of its sides.
one of the most basic curvilinear geometric shapes, the surface formed by the points at a fixed distance from a given straight line, the axis. The solid enclosed by this surface and by two planes perpendicular to the axis. The surface area and the volume have been known since deep antiquity.
