When two planes intersect, their intersection is a line. Unlike two lines that cross at a single point, two flat surfaces meeting in space share a common straight path.
Conditions: Two distinct planes are given.; The planes are not parallel or skew; they intersect.

To name a ray, write the endpoint first, followed by a second point in the direction the ray extends, and place a one-way arrow above the letters. The arrow symbol always points to the right in notation, regardless of the drawn direction.
Conditions: The object being named is a ray.; Two points are available: the endpoint and a direction point.
