A cone has many important features, starting with a circular base and curved side. The apex is defined as the tip of the cone, where the curved surface meets itself at a point. The axis of a cone refers to an imaginary straight line that passes through the center of the base and the apex. Around this line, a cone has rotational symmetry, meaning it is the same shape no matter how a person rotates it. Finally, a cone will have different steepness from the base to the apex, depending on how high the apex is.
