Geometry Shapes for Kids
What is Geometry Shape?
Any object with a fixed structure is called a geometric shape. These geometric shapes are made by combining a specific number of curves, points, angles, and lines.
Shapes can be either 2D (2-dimensional) or 3D (3-dimensional).
2D and 3D Geometric Shapes
Two-dimensional (2D) shapes are flat structures with two measurements, i.e., height and length. Two-dimensional (2D) shape examples: circle, rectangle, square, triangle, pentagon, quadrilateral, hexagon, and octagon.
Three-dimensional (3D) shapes are solid structures with three measurements, i.e., height, length, and depth. Three-dimensional (3D) shape examples: cube, cuboid, sphere, cone, pyramid, rectangular prism, and cylinder

Geometry Shapes: Types and Properties
Circle: It is a 2-dimensional shape. Circles have only one side and no corner. It is made of curves that are all connected.
There are three main parts of a circle: the radius, the diameter, and the circumference.
Triangle: A triangle is a 2-dimensional shape. It has three sides and three vertices. Each vertex forms an angle. There are three angles in a triangle. The sum of the angles of a triangle is always 180 degrees.
There are four types of triangles: equilateral triangles, isosceles triangles, scalene triangles, and right triangles.
Square: A square has four straight sides and four corners. All four sides of the square are equal to each other. The opposite sides are parallel to each other. The two diagonals of the square are equal to each other. The sum of all the interior angles is equal to 360 degrees.
Rectangle: Rectangles have four sides and four corners. It has two long sides and two short sides. The opposite sides are parallel to each other. The sum of all the interior angles is equal to 360 degrees.
Pentagon: A pentagon has five straight sides and five corners. The sum of the interior angles is equal to 540°.
Hexagon: A hexagon has six straight sides and six corners. It has six vertices.
The sum of the interior angles is equal to 720°.
Heptagon: A heptagon has seven straight sides and seven corners. It has seven vertices. The sum of the interior angles is equal to 900°. It has 14 diagonals.
Octagon: An octagon has eight straight sides and eight corners. It has eight vertices. All sides and all angles are equal. The sum of the interior angles is equal to 1080°.
Oval: An oval is a closed shape. It has no straight lines. The oval has only one side and no corners or vertices.
Rhombus: A rhombus has four sides and four corners. All four sides are equal in length. The opposite sides are parallel to each other.
Parallelogram: Parallelograms have four sides and four corners. The opposite sides are equal and parallel.
Trapezoids: Trapezoids have four straight sides and four corners. It has two long sides and two short sides. It has two parallel sides and two non-parallel sides.
Sphere: A sphere is a 3-dimensional shape with one curved surface. A sphere does not have any edges or vertices. The distance from the center of the sphere to any point on the surface is equal.
Cube: A cube is a 3-dimensional shape. It has 6 faces, 8 vertices, and 12 edges. All the faces of the cube are square.
Cone: Cones have one circular face and 1 vertex. It has a pointed edge at the top called the apex.
Cylinder: Cylinders have 2 flat and circular faces, 2 curved edges, and 1 curved surface.
