Intersecting Lines and Planes Title Card

These four points are are coplanar.

Because the four points are coplanar, the lines intersecting these points are also coplanar.

Two coplanar lines intersect at a point.

When two planes intersect, they intersect along a line.

There are many real-world examples of intersecting lines and planes.

See the two intersecting planes? See how they intersect at a line?

The tracks of two skaters form intersecting lines.
