Question

1. line point rotational none

Explanation:

Step1: Check for line symmetry

A line of symmetry divides a figure into two mirror - image halves. This figure has a vertical line of symmetry.

Step2: Check for rotational symmetry

When rotated \(180^{\circ}\) around the center point (the point where the two semi - circular parts meet), the figure maps onto itself.

Answer:

Line, Rotational
