The image contains several geometry problems related to three-dimensional shapes, such as prisms, cubes, and pyramids. Let's solve each of these problems step-by-step:

### Problem 1:
It mentions angles formed by certain line segments within a triangular prism \(ABC.DEF\). We need to identify which line segments create angles with each other. This involves determining the geometric properties of the given prism.

### Problem 2:
The problem involves a cube \(ABCD.EFGH\) and asks for the angles formed between different lines and planes in the cube. Understanding the relationships between lines within the cube will allow us to find the angles.

### Problem 3:
This problem focuses on a regular triangular pyramid (tetrahedron) \(TABC\). It asks for the angles formed between the planes, which requires knowledge of dihedral angles in tetrahedrons.

### Problem 4:
The problem involves identifying angles between various edges and diagonals in another cube \(ABCD.EFGH\). Determining these angles requires an understanding of 3D geometry principles.

### Problem 5:
It discusses identifying angles between certain lines in a square-based pyramid \(T.ABCD\).

Each problem involves calculating or identifying angles between different line segments or planes in three-dimensional shapes.
