Answer with explanation:
We know that the symmetry of a figure means that when a figure is moved, flipped or reflected along any of the line, point or plane than it retain'sit's shape or structure.
Now we are given a geometrical shape as:
CIRCLE
Now when the circle is rotated along a point then it's shape is retained.
- so,circle is symmetrical about a point.
a circle is symmetrical about it's center.
- same is the case of a line.
a circle is symmetrical is about it's diameter.
and a plane symmetry is for a three dimensional figure.
Hence, circle is symmetrical about Point and a line.
