Question Analysis

This question involves determining the number of triangular faces in the 2D net of a triangular pyramid. The main focus is on understanding the structure of a triangular pyramid (tetrahedron) and how its 3D shape unfolds into a 2D net.

 

Key Concept Explanation:

Triangular Pyramid: A triangular pyramid, also known as a tetrahedron, is a 3D shape that has a triangular base and three triangular lateral faces.

 

Step-by-Step Solution:

When we create a net for a triangular pyramid, we are essentially laying out all of its faces flat. The base triangle and the three lateral triangles are all part of the net. So in tot...
