Geometric Shapes in Maths Last Updated : 07 Apr, 2025 Comments Improve Suggest changes Like Article Like Report Geometric shapes are mathematical figures that represent the forms of objects in the real world. These shapes have defined boundaries, angles, and surfaces, and are fundamental to understanding geometry. Geometric shapes can be categorized into two main types based on their dimensions:2D Shapes (Two-dimensional shapes) – Shapes with only length and width, lying flat on a plane (e.g., squares, circles).3D Shapes (Three-dimensional shapes) – Shapes with length, width, and height, giving them volume and depth (e.g., cubes, spheres).Additionally, geometric shapes can be further classified based on their symmetry:Regular Shapes: These are symmetric shapes, where all sides and angles are equal (e.g., squares, equilateral triangles).Irregular Shapes: These shapes lack symmetry and have sides and angles of different lengths and measures (e.g., scalene triangles, freeform shapes).Introduction to 2D ShapesThis section introduces 2D shapes, covering their key properties and classifications, including triangles, squares, circles, and polygons.TriangleSquareRectangleCircleParallelogramRhombusTrapeziumPentagonHexagonHeptagonOctagonEllipsePolygonsIntroduction to 3D ShapesThis section introduces 3D shapes, covering their key properties and classifications, including cubes, spheres, pyramids, and more.CubeCuboidSphereCylinderConePolyhedronPrismPyramidHemisphereKey Concepts of 2D and 3D ShapeThis section explores the key concepts of 2D and 3D shapes, including how to calculate area and perimeter for 2D shapes, and surface area and volume for 3D shapes.
