A circle does not have any lines or corners. Circle: A circle is a closed two-dimensional geometric figure that is round in shape.Rectangle: A rectangle is a four-sided, two-dimensional geometric shape in which the length of the opposite sides is equal.For example, the shapes of a chessboard and a carrom board. Square: A square is a two-dimensional geometric shape that is formed by four sides of equal length.For example, a sketch of a slice of pizza, the shape of nachos, etc. Triangle: A triangle is a closed two-dimensional geometric shape with three sides.Let us learn about the five basic two-dimensional geometric shapes. Look at the chart given below which represents different two-dimensional and three-dimensional geometric shapes. A triangle can be formed by joining three-line segments and so on. Thus, based on the number and arrangement of the lines we can make different types of geometric shapes and figures, for example, by joining four line segments a rectangle shape is formed. To draw any of these geometric figures, we have to start with a line, a curve, or a line segment. They are solid structures with 3 dimensions. The z-axis represents the height of the object. Three-dimensional: These are 3D shapes that have an x-axis, y-axis, and z-axis.For example, triangle, square, rectangle, etc.

They are flat structures with 2 dimensions.

Two-dimensional: These are 2D shapes that have only the x-axis and y-axis.There are two types of geometric shapes, classified as: When an object or a shape is connected with both ends it is considered a closed geometric shape. In geometry, when an object or a shape is not connected with both ends, it is considered an open geometric shape.
