Answer:
The planes that contain the line AD are
1) Plane represented by bounded area ABCD
2) Plane represented by bounded area ADHE
Step-by-step explanation:
The line AD is located at the boundary of the planes ABCD and ADHE and as such is contained in the two planes.
A plane is defined as a flat surface in two dimensional space that has a linear vector boundary on alternate sides
A plane can be specified by a letter written in capitals, or by use of the letters at three non collinear points on the plane, such as plane P or plane ABC.
