Three Dimensional Worksheets
What is the Difference Between Two and Three-Dimensional Shapes? A two dimensional shapes refer to the shapes that have only length and height as its dimensions. Because two-dimensional shape lie on a flat surface, they are also known as plane figures or plane shapes. While they have an area, two-dimensional shapes have no volume. It is plotted in a graph on the x- and y- axes. Examples: The Triangle, The Square, The Circle, The Rectangle. Whereas a three dimensional shape has length, height, and width (depth) as its dimensions. It is plotted in a graph on the x-, y- and z- axes. Examples: Dice - Cube, Shoe Box - Cuboid or Rectangular Prism, Globe - Sphere, Soda Can - Cylinder.
Similar shapes have the same qualities but differ in size. Their angles are corresponding and their sides are in proportion to each other. Two triangles are considered similar if all three angles of one are equal to all three angles of the other.
