- Rectangles – A rectangle has two lines of symmetry: one vertical and one horizontal line that bisect the rectangle.

The vertical line is a line of symmetry because it divides the shape into two equal halves that are mirror images of each other. Draw a horizontal line through the marked center and check for line symmetry.
A rectangle has two lines of symmetry (LoS) shown below using a dashed line. In the diagram on the left, the vertical line of symmetry splits the rectangle into two equal shapes, in the diagram on the right the horizontal line of symmetry splits the rectangle into two equal shapes.

It is an imaginary vertical line that goes from top to bottom (or vice-versa) in an object and divides it into right and left mirror halves. For example, a club shape has a vertical line of symmetry.
It is an imaginary horizontal line that goes from right to left (or vice-versa) in an object and divides it into top and bottom mirror halves. For example, an arrow has a horizontal line of symmetry.
It is an imaginary diagonal or skew line that goes slanting in an object and divides it into mirror halves, as in the case of a square.
This Maths article shows how the mirror line can help you to recognise vertical lines of symmetry on shapes and letters.
This Maths article shows how to find lines of symmetry on shapes and practise drawing them.
If the line of symmetry is such that it divides a geometrical shape into two identical halves in a vertical manner, it is known as a vertical line of symmetry. A geometrical figure is said of having one line of symmetry if it is symmetrical about one line of axis only.
Nov 28, 2022 · We can draw a line of symmetry from the top vertex to the centre base, similar to the isosceles triangle. We can also draw lines of symmetry from the other two vertices to the opposite side. An equilateral triangle, therefore, has 3 lines of symmetry.
