Question

Line of symmetry for an angle is its __________.

Answer 1

Explain line of symmetry for an angle:

line of symmetry: The line of symmetry can be defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves

First, let us draw a suitable diagram.

Here, in the diagram, $OC$ is the bisector of $\angle AOB$.

It means that the line segment $OC$ divides the $\angle AOB$ in two equal parts.

It means that $\angle AOC$ and $\angle COB$ are symmetrical.

Thus, it can be concluded that $OC$ is the line of symmetry of $\angle AOB$.

Hence, Line of symmetry for an angle is its bisector.
