• So, this train arrived at

## Question 53

### Write in Short

For the shape shown,

Write down

(a) The number of lines of symmetry,

(b) The order of rotational symmetry

### Explanation

Here,

(a) If we can reflect a figure over a line and the figure appears unaffected, then the figure has reflection symmetry or line symmetry.

• The line that you reflect over is called the line of symmetry.
• A line of symmetry divides a figure into two mirror-image separations.
• The number of lines of symmetry of a regular hexagon is because it has six equal sides by reflecting all we can get same image as it is.

(b) The order of rotational symmetry of a regular hexagon is also becausewhen we rotate it, it will see in same position as shown in given figure for six times.
