Question

name the plane that contains points a, d, and e.

Explanation:

To name the plane containing points \( A \), \( D \), and \( E \), we analyze the diagram. Plane \( T \) is the lower plane (as per the visual), and points \( A \), \( D \), \( E \) lie on this plane. Other options: Plane \( D \) is not a valid plane name (planes are named by letters like \( T \), \( S \) or by three non - collinear points), Plane \( S \) is the upper plane (points \( B \), \( C \) are on it), and the line names (\(\overleftrightarrow{BC}\), \(\overleftrightarrow{DE}\)) and Plane \( C \) are incorrect. So the plane containing \( A \), \( D \), \( E \) is Plane \( T \).

Answer:

Plane \( T \)
