Let's analyze the geometry diagram and answer the questions based on it.

1. Name four points: From the diagram, the four points visible are:

   • $A$
   • $B$
   • $C$
   • $D$ (Although $E$ and $T$ are also present, only four points were requested.)

2. Name two lines: The two lines can be identified as:

   • Line $\overline{AB}$
   • Line $\overline{DE}$

3. Name the plane that contains points $A$, $B$, and $C$: The plane containing these points appears to be the top plane in the figure, which we can name as:

   • Plane $ABC$

4. Name the plane that contains points $A$, $D$, and $E$: These points lie on the lower plane, so this is:

   • Plane $ADE$

If you need any clarifications or more details, feel free to ask! Here are five related questions to extend your understanding:

1. How can you confirm if three points are collinear or coplanar?
2. How many points are needed to define a unique plane?
3. What is the geometric term for the intersection of two planes?
4. Can lines $AB$ and $DE$ be considered parallel in this diagram?
5. How do we name a line that lies in a plane?

Tip: Always ensure that points used to define a plane are non-collinear to avoid ambiguity!
