Point of rotation
Center 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.

The least angle at which the figure may be rotated to coincide with itself is the angle of symmetry.
If it says rotated it's true If it says reflected it is false
