Question
Which solid figure has a base that is a polygon and triangular faces that meet at a vertex?
A. Prism
B. Cylinder
C. Pyramid
D. Cone
Solution
To determine which solid figure has a base that is a polygon and triangular faces that meet at a vertex, let's analyze the options given:
-
Prism: A prism has two parallel polygonal bases and rectangular faces connecting them. It does not have triangular faces meeting at a vertex.
-
Cylinder: A cylinder has two circular bases and curved surfaces. It also does not have triangular faces.
-
Pyramid: A pyramid has a polygonal base and triangular faces that converge at a single vertex (the apex). This description matches the given criteria.
-
Cone: A cone has a circular base and a curved surface that meets at a vertex, but it does not have a polygonal base.
Conclusion
The solid figure that has a base that is a polygon and triangular faces meeting at a vertex is C. Pyramid.
