Question

The definitions of parallel lines and intersecting lines are applicable only when the lines are:

Options

• Of equal length

• In the same plane (coplanar)

• Perpendicular to each other

• Curved or bent

Answer 1

In the same plane (coplanar)

Explanation:

For two lines to be either parallel or intersecting, they must lie in the same plane.
If they are not coplanar, they are called skew lines, which neither meet nor are parallel.
