# Geometry Videos

Geometry is the pure mathematics of: points, lines, curves and surfaces.

## Midpoint (En Español)

SLE CGT.5.G.1 – Use coordinate geometry to find the distance between two points, the midpoint of a segment, and the slopes of parallel, perpendicular, horizontal, and vertical lines.
