2D and 3D Shape Properties Worksheet
Understanding the properties of 2D and 3D shapes is a fundamental concept in mathematics, and it's essential for students to recognize and identify these shapes. In this article, we will explore the properties of 2D and 3D shapes and provide a worksheet to help students practice and reinforce their knowledge.
What are 2D Shapes?
Twodimensional (2D) shapes are flat shapes that can be drawn on a piece of paper. They have only two dimensions: length and width. Examples of 2D shapes include:
 Squares
 Rectangles
 Triangles
 Circles
 Hexagons
 Octagons
Properties of 2D Shapes
2D shapes have several properties that distinguish them from one another. These properties include:
Number of Sides
 A square has 4 sides
 A rectangle has 4 sides
 A triangle has 3 sides
 A circle has no sides (it's a continuous curve)
Number of Corners
 A square has 4 corners
 A rectangle has 4 corners
 A triangle has 3 corners
 A circle has no corners
Angles
 A square has 4 right angles (90 degrees each)
 A rectangle has 4 right angles (90 degrees each)
 A triangle has 3 angles (sum of angles is 180 degrees)
 A circle has no angles
What are 3D Shapes?
Threedimensional (3D) shapes are solid shapes that occupy space. They have three dimensions: length, width, and height. Examples of 3D shapes include:
 Cubes
 Rectangular prisms
 Triangular prisms
 Spheres
 Cones
 Cylinders
Properties of 3D Shapes
3D shapes have several properties that distinguish them from one another. These properties include:
Number of Faces
 A cube has 6 faces
 A rectangular prism has 6 faces
 A triangular prism has 5 faces
 A sphere has 1 face (a continuous curved surface)
Number of Edges
 A cube has 12 edges
 A rectangular prism has 12 edges
 A triangular prism has 9 edges
 A sphere has no edges
Number of Vertices (Corners)
 A cube has 8 vertices
 A rectangular prism has 8 vertices
 A triangular prism has 6 vertices
 A sphere has no vertices
