There are many shapes in geometry based on their dimensions. Circle, Triangle, Square, Rectangle, Kite, Trapezium, Parallelogram, Rhombus and different types of polygons are the 2-d shapes. Cube, Cuboid, Sphere, Cone and Cylinder are the basic three-dimensional shapes.

Shapes are the external boundaries or outlines of objects. They can be two-dimensional (2D) or three-dimensional (3D). Basic 2D shapes include squares, rectangles, circles, triangles, and polygons. Basic 3D shapes include cubes, spheres, cylinders, cones, and pyramids.
