Different geometrical shapes can be formed using 3 or more straight lines.The point where the two lines meet is called a corner or vertex.
When 2 lines meet at a point, they form an angle at that point.
Hence each shape will have different angles at each of its vertex.
Here we will learn different closed and open shapes and the angles they have.
