Center of rotation
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.

When u rotated a figure 180 is the reflection the same
A point of symmetry is a specific point in a geometric figure such that if the figure is rotated 180 degrees around that point, it maps onto itself. This means that for every point on one side of the figure, there is an equivalent point on the opposite side at the same distance from the center. Common examples include circles and certain shapes like stars, where the center serves as the point of symmetry.
well if you rotated it upside down then it would be a face with a uni brow.

A figure can be rotated through any angle of your choice.

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.
