  4. Definitions • Collinear -lying on or passing through a single straight line • Coplanar - lying in the same plane • Parallel - lines that are always the same distance apart, never meet • Perpendicular - lines that intersect to form a right angle • Skew Lines - two straight lines that do not lie in the same plane, are not parallel, and do not intersect • Midpoint -the point on a line that is halfway between the endpoints • Bisect - to divide something into two exactly equal parts
