Question

The order of rotation of a line segment is

• A. 4
• B. 3
• C. 1
• D. 2

Answer 1

Answer: (D)

Order of rotation is termed as number of times a figure looks the same in complete, ${360}^{\circ }$ rotation and it can also be calculated using angle of rotation.

Order of rotation of a figure can be given by$\frac{{360}^{\circ }}{\text{angle of rotation}}$

The angle of rotation of a line segment is ${180}^{\circ }$.

So the order of rotation of a line segment $=\frac{{360}^{\circ }}{{180}^{\circ }}$

$=2$
