Geometry

Question Analysis

This question assesses whether common 3D shapes can be represented by 2D nets. The main focus is on understanding the geometric properties of each 3D shape and how their surfaces can be flattened into a 2D pattern.

 

Key Concept Explanation:

A 2D net is a flat layout of the faces of a 3D object that can be folded to form the 3D shape. Different 3D shapes have distinct ways of creating their nets based on the shape and number of their faces.

 

Option Analysis

A cylinder has two circular bases and a rectangle (representing the curved surface when unrolled).

 

A cone has a circular base and a sector of a circle (representing the curved surface).

 

A rectangular prism has six rectangular faces....
