Distinguish between two-dimensional (2D) plane figures and three-dimensional (3D) solid shapes.
Distinguish between two-dimensional (2D) plane figures and three-dimensional (3D) solid shapes.
Analyze the Given Items
Examine the geometric properties of Circle, Square, Sphere, and Triangle. Circle, Square, and Triangle are flat, two-dimensional geometric shapes lying entirely on a plane. Sphere is a solid, three-dimensional geometric object.
Identify the Odd One Out
Since Circle, Square, and Triangle are 2D shapes while Sphere is a 3D shape, Sphere is the odd one out.
A: Circle is a 2D shape, not the odd one out. B: Square is a 2D shape, not the odd one out. D: Triangle is a 2D shape, not the odd one out.
C is correct because Sphere is a three-dimensional (3D) solid figure, whereas Circle, Square, and Triangle are two-dimensional (2D) plane figures.
In classification questions involving geometry, always check dimensions (2D vs 3D), number of sides, or symmetry as primary classification parameters.
