Transcribed Image Text:### Educational Content on Rays in Geometry
#### Diagram Explanation:
The diagram provided is a geometric representation of a plane with points labeled as D, E, F, G, and H. This plane is depicted in blue and shows several points and lines:
- **Plane DEFG:** The quadrilateral making up the main plane.
- **Lines and Points:** Points D, E, F, and G lie on the plane, with point E at the center intersecting other lines.
- **Perpendicular Line to the Plane:** Point H appears above the plane, connected by a dashed line suggesting perpendicularity to the plane passing through point E.
#### Exercise:
**Using the diagram, name 3 rays with a common endpoint.**
Options provided:
1. \( \overrightarrow{EF} \)
2. \( \angle HEF \)
3. \( \overrightarrow{ED} \)
4. \( \overrightarrow{DF} \)
5. \( \overrightarrow{EH} \)
##### Correct Answer:
The correct rays that have a common endpoint, which is point E, are:
- \( \overrightarrow{EF} \)
- \( \overrightarrow{ED} \)
- \( \overrightarrow{EH} \)
These rays all start from point E and extend towards points F, D, and H respectively. This illustrates how multiple rays can originate from a single point, demonstrating the concept of rays in geometry.
