Just like parallel lines,parallel Planes are
two planes that do notintersect.

Vocabulary Skew Lines
Two or more lines that do not intersect but are not coplanar. Transversal
A line that intersects two or more lines in a plane at different points.
All lines intersect at one point. No line is a transversal.
The red line intersects theother lines at 2 different points.
Skew Lines - don't intersectnot coplanar
