Question

Angle of rotation of a figure is 40° . What is the number of lines of symmetry ​

Answer 1

Answer:

9

Step-by-step explanation:

360/40=9

We can find no. of lines of symmetry by dividing 360 by given angle

Answer 2

Given,

Angle of rotation of a figure=40°

To Find,

Number of lines of symmetry.

Solution

We know lines of symmetry is the axis which passes through the Centre of the shape of the object by dividing into identical halves.

So we have to calculate lines of symmetry from the angle of rotation

For this we have the formula,

Number of lines of symmetry=360°/angle of rotation

As a result, 360°/40°=9 number of lines of symmetry

Hence, number of lines of symmetry is 9.
