there are three main characteristics of a parabola. these are:
1. vertex: the point at the apex of a parabola
2. x- intercepts: the points at which the parabola intersects or touches the x axis.
3. face: if the parabola is in the form of the letter "u" then it's face is upwards. if the parabola is the in form of the inverted letter "u" then it face downwards :D

Circles, parabolas, ellipses,and hyperbolas are called conic sections because you can get those shapes by placing two cones - one on top of the other - with only the tip touching, and then you cut those cones by a plane. When you move that plane around you get different shapes. If you want to see an illustration of these properties, click on the link below on the related links section.
