2D and 3D Shapes Worksheet by Teach Simple
In geometry, 2D shapes (2 dimensional shapes) can be defined as plane figures that are completely flat and have only two dimensions - length and width. They do not have any thickness and can be measured only by the two dimensions. In comparison to these, a 3D (three-dimensional) shape has three dimensions - length, width, and height.

Properties of 3D shapes. A sphere has 1 curved surface. A hemisphere has 1 face, 1 curved surface and 1 edge. A cone has 1 face, 1 curved surface, 1 edge and 1 vertex. A tetrahedron, or triangular-based pyramid, has 4 faces, 6 edges and 4 vertices. A square-based pyramid has 5 faces, 8 edges and 5 vertices.

The prior difference between the 2D and 3D shapes is that in 2D shapes only two axis are incorporated x and y-axis. On the other hand, in 3D shapes, the three axis x, y and z-axis are covered. Square, circle, triangle, rectangle are the various 2D shapes while cube, sphere, cuboid, are the 3D shapes. The plan in engineering drawing, which.

You might be confused by the differences between 2D and 3D shapes. There are some ways to measure an object in space. 3D objects can be measured in length, width, and height. 3D shapes, unlike 2D shapes, do not have a flat surface. Means they have depth. Two-dimensional shapes have two dimensions, while three-dimensional shapes have three.

2D Shapes. In geometry, a shape or a figure that has a length and a breadth is a 2D shape. In other words, a plane object that has only length and breadth is 2 dimensional. Straight or curved lines make up the sides of this shape. Also, these figures can have any number of sides. In general, plane figures made of lines are known as polygons.

Some examples of 2D shapes are circles, triangles, hexagons, octagons and quadrilaterals. A quadrilateral is a four-sided shape with straight sides. A rhombus, a kite, a square and a rectangle are all examples of quadrilaterals. 2D shapes are classed as either polygons or non-polygons. A polygon is a closed 2D shape that only has straight sides.

2d Shapes: 3d Shapes: It is a shape surrounded by three or more straight lines in a plane and sometimes with a closed curve. If a shape is surrounded by a no. of surfaces or planes then it is a 3D shape. These shapes have no depth or height. These are also called solid shapes and unlike 2D they have height or depth.
