A Parable about Parabolas
Name:
What is a parabola?
It is geometrically defined by a set of points or locus of points that are
equidistant from a point (the focus) and a line (the directrix).
To see this idea visually try
drawing a straight line at the
bo

Symmetries
A shape has a vertical line of
symmetry if you can fold it in half
vertically and have the halves match up.
On a scrap sheet of paper try folding the
letter M in half.
A shape has a horizon
