Objects are coplanar if they lie in the same plane. In a coordinate plane, parallel lines can be identified as having equivalent slopes. Indicate the appropriate response to the following statement. This means that skew lines are never coplanar and instead are noncoplanar. In geometry, parallel lines are coplanar infinite straight lines that do not intersect at any point. Note that u and v are parallel if and only if they have the same or opposite directions, which happens exactly when u and v are at an angle of 0 or .
