Answer:
In geometry, 2d shapes and 3d shapes are explained widely to make you understand the different types of objects you come across in real life. These shapes have their own pattern and properties. Depending on many factors, such as angle, sides, length, height, width, area, volume, etc., the shapes can vary. These 2D and 3D shapes have been taught to us since our primary classes. Let us learn various types of two-dimensional shapes here, in this article.

Characteristics of 4types of 2D shapes :
Circle
A circle is a closed 2d figure in which the set of all the points in the plane is equidistant from a given point called “center”.
Triangle
A triangle is a three-sided polygon (2d Shape) which has three edges and three vertices. The sum of all the three angles of a triangle is equal to 180°.
Rectangle
A rectangle is a 2d shape which has four sides, where the opposite sides are equal and parallel to each other. All the angles of a rectangle are equal to 90°.
Octagon
An octagon is an eight-sided polygon which can be either regular or irregular. It is a 2d shape which has eight angles. The sum of all the interior angles of an octagon is 1080°
Characteristics of 4types of 3D shapes:
Cube
A cube is a solid or three-dimensional shape which has 6 square faces. The cube has the following properties.
All edges are equal
8 vertices
12 edges
6 faces
Cuboid
A cuboid also called a rectangular prism, where the faces of the cuboid are a rectangle in shape. All the angle measures 90 degrees. The cuboid has
8 vertices
12 edges
6 faces
Cylinder
A cylinder is defined as a three-dimensional geometrical figure which has two circular bases connected by a curved surface. A cylinder has
No vertex
2 edges
2 flat faces – circles
1 curved face
Cone
A cone is a three-dimensional object or solid, which has a circular base and has a single vertex. The cone is a geometrical figure that decreases smoothly from the circular flat base to the top point called the apex. A cone has
1 vertex
1 edge
1 flat face – circle
1 curved face
Sphere
A sphere is a three-dimensional solid figure which is perfectly round in shapes and every point on its surface is equidistant from the point is called the center. The fixed distance from the center of the sphere is called a radius of the sphere. A sphere has
No vertex
No edges
1 curved face
