A circle does not have any lines or corners.


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. Two-Dimensional Geometric Shapes - 2D Geometric Shapes Observe 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. For example, by joining four line segments a rectangle shape is formed. Thus, based on the number and arrangement of the lines we can make different types of geometric shapes and figures. To draw any of these geometric figures, we need 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 geometric shapes: 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 geometric shapes: 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.
