**29.** Which two-dimensional figure results from a pentagonal pyramid being sliced vertically 

and perpendicular to the base? 

A Triangle 

B Square 

© Circle 

When a pentagonal pyramid is sliced vertically and perpendicular to the base, the resulting two-dimensional figure would be a **triangle**. This is because the cross-section cuts through the apex of the pyramid and the base, creating a triangular shape.

Thus, the correct answer is:

**A) Triangle**

Here are 5 related questions for further exploration:
1. What would the cross-section look like if the pyramid were sliced horizontally?
2. How would the cross-section change if the pyramid had a different base, such as a square?
3. Can a pentagonal pyramid have a cross-section that results in a trapezoid?
4. What is the volume formula for a pyramid with a regular pentagonal base?
5. How does the slant height affect the appearance of vertical cross-sections in pyramids?

**Tip:** When slicing 3D shapes, the orientation and position of the slice can significantly change the resulting 2D cross-section.
