Point of rotation
The least angle at which the figure may be rotated to coincide with itself is the angle of symmetry.
A point or a line segment can be a preimage of itself because a line can be reflected or rotated.
If it's an *equilateral* triangle, a triangle. Check out quadrilaterals (squares, rectangles), then *equilateral* pentagons, hexagons, etc. Generally, an equilateral polygon needs only rotate (360/number of sides) degrees to coincide.

It is called a rotation.
When u rotated a figure 180 is the reflection the same
well if you rotated it upside down then it would be a face with a uni brow.

Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.
