![]() All these shapes have curved faces, and hence they are called curved solids or non-polyhedrons. A sphere is a geometrical object in three-dimensional space that is the surface of a ball. For example, cones have a circular base that narrows smoothly from the circular base to the point called the apex.Ī cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. These regular polyhedrons are also known as the platonic solids, whose faces are identical to each face.įor example, the most commonly used example of a polyhedron is a cube, which has 6 faces, 8 vertices, and 12 edges.Īpart from polyhedrons, there are 3D shapes with curved shapes such as the sphere, cone, cylinder, etc. Some other examples of regular polyhedrons are tetrahedron, octahedron, dodecahedron, icosahedron, and so on. The most common examples of polyhedral are cube, cuboid, pyramid, and prism. Like polygons in two-dimensional shapes, polyhedrons are also classified into regular and irregular polyhedrons and convex and concave polyhedrons. It must have the corners, called vertices.It should have flat sides are called the faces.Polyhedrons should have straight edges.Polyhedron are straight-sided solids, which has the following properties: Side view of pyramid will look like a triangular shape for left and right side.

And since 'hexa' contains the letter 'x', you know it is six. A 2D shape, also written as a two-dimensional shape is a shape that has length and width but no depth. 6 hexa - just remember that if it starts with a 'h', it's either 6 or 7. 4 tetra - if you play tetris, you'll know it 5 penta - sorry, I don't really have one for this.
