Which of the following shapes have the most number of lines of symmetry?
Square
A figure is said to have a line of symmetry or linear symmetry if there exists a line which divides the figure into two identical halves such that they coincide when folded along this line.
A rectangle has 2 lines of symmetry, whereas an isosceles triangle and kite have just 1 line of symmetry each. A square has 4 lines of symmetry as shown in the figure. Hence, it has the most lines of symmetry than others.
