2D shapes are flat and exist only on a surface, like circles, squares, and triangles. They have length and width but no depth. 3D shapes are solid objects with volume, such as spheres, cubes, and pyramids. They have length, width, and height. Understanding both types helps you recognize shapes everywhere in the real world.

A hexagon has six sides and six angles. The word comes from Greek: 'hex' means six and 'gon' means angle. Hexagons are incredibly common in nature. Honeycomb cells are perfect hexagons, and snowflakes often form hexagonal patterns. This shape is also very strong, which is why it's used in engineering.

A polygon is a closed shape made up of straight line segments connected end to end. These line segments are called sides, and the points where they meet are called vertices or corners. Polygons cannot have curved sides, so circles and ovals are not polygons. Triangles are the simplest polygons with just three sides.

Triangles are incredibly strong because their three-sided structure distributes weight evenly and resists bending. This is why triangles are used in bridge construction, roof trusses, and tower designs. The rigidity of triangles makes them ideal for supporting heavy loads, which is why engineers and architects love using them in building structures.

A square is a special type of rectangle where all four sides are exactly equal in length. A rectangle has four right angles but only opposite sides need to be equal. Every square is a rectangle, but not every rectangle is a square. Both shapes have four 90-degree angles and parallel opposite sides.

The sum of interior angles depends on the number of sides. A triangle's angles add up to 180 degrees, a square or rectangle's angles add up to 360 degrees, and a pentagon's angles sum to 540 degrees. The formula is: total degrees equals (number of sides minus two) times 180 degrees.
