cube, cuboid, cone, prism, pyramid, sphere. (Differentiate between the regular and irregular)

See following response to your post. Thanks for asking.

Sure! Let's differentiate between regular and irregular figures for the given shapes:

1. Cube:
- Regular cube: All sides (faces) of a cube are equal in length and all angles are right angles.
- Irregular cube: If any of the sides or angles are not equal, then the cube is irregular.

2. Cuboid:
- Regular cuboid: All six faces of a cuboid are rectangles, and opposite faces are equal in size.
- Irregular cuboid: If any of the faces are not rectangles or opposite faces are not equal, then the cuboid is irregular.

3. Cone:
- Regular cone: The base of a cone is a regular polygon, and the height is perpendicular to the base.
- Irregular cone: If the base is not a regular polygon or the height is not perpendicular to the base, then the cone is irregular.

4. Prism:
- Regular prism: The bases of a prism are regular polygons, and the lateral faces are parallelograms.
- Irregular prism: If the bases are not regular polygons or the lateral faces are not parallelograms, then the prism is irregular.

5. Pyramid:
- Regular pyramid: The base of a pyramid is a regular polygon, and the height is perpendicular to the base.
- Irregular pyramid: If the base is not a regular polygon or the height is not perpendicular to the base, then the pyramid is irregular.

6. Sphere:
- Regular sphere: A sphere is a perfectly symmetrical 3D shape, such that all points on its surface are equidistant from its center.
- There is no irregular sphere since it would not be a sphere if it deviates from perfect symmetry.

Remember, the regularity or irregularity of a shape depends on specific criteria that define that shape.
