Question

A solid is cut by a plane that is perpendicular to its base, forming a two-dimensional cross section in the shape of a triangle. Which of the following solids could have resulted in that cross section?
A. circula
B. triangulo
C.cilindro

Answer 1

To determine which solid could result in a triangular cross section when cut by a plane that is perpendicular to its base, let's analyze each option:

A. **Circulo (Circle)**: A circular solid (like a sphere) would not produce a triangular cross section when cut perpendicularly to its base, as the cross section would typically be circular.

B. **Triangulo (Triangle)**: A triangular solid (like a triangular prism) could produce a triangular cross section when cut perpendicularly to its base, as the cross section will maintain the same shape as the solid's base, which is a triangle.

C. **Cilindro (Cylinder)**: A cylinder, when cut perpendicularly to its base (which is circular), would produce a circular cross section, not triangular.

Based on this analysis, the solid that could result in a triangular cross section when cut by a plane perpendicular to its base is:

**B. Triangulo**.
