I see that you've uploaded two images related to geometry exercises. These images contain problems that involve three-dimensional shapes and geometric relationships between lines and planes.

Let's go through the content step by step:

1. First Image (related to the rectangular box)

   • The first problem presents a 3D shape (a rectangular box or cuboid) and asks questions about the spatial relationships between different lines and planes within the shape.
   • The questions are:
     • a. How is line AG positioned relative to line BH?
     • b. Name the plane that passes through lines BC and EH.
     • c. Name the line parallel to the plane ABGH.

2. Second Image (related to planes and lines)

   • The second image provides another geometry exercise involving two parallel planes, denoted by α and β. Lines p and q lie on these planes, and the two planes intersect at point T.
   • The questions are:
     • a. How is point T positioned relative to plane β?
     • b. How is line p positioned relative to line r?

Do you want a detailed solution to any specific question, or help with understanding the geometry concepts in these problems?

Feel free to ask for further clarification or solutions to any part!

Here are some related questions to help deepen your understanding:

1. How do you identify the relationship between two skew lines in a 3D figure?
2. What is the significance of parallel lines and planes in geometric problems?
3. How do you determine the intersection of two planes?
4. What properties of lines can help you determine their position relative to planes in 3D space?
5. Can you visualize the projection of a point onto a plane? How would you do it?

Tip: When working with three-dimensional geometry, drawing the figure and labeling the points, lines, and planes can make the relationships much clearer.
