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.
An equivalent transformation to rotating a figure 90 degrees counterclockwise can be achieved by reflecting the figure across the line (y = x) and then reflecting it across the x-axis. This combination of reflections results in the same final orientation as the 90-degree counterclockwise rotation.
When a figure is translated or rotated, the original figure and its image maintain the same size and shape. Both figures retain their corresponding angles and side lengths, making them congruent. Additionally, the orientation may change during rotation, but the relative positions of the points remain consistent in translation.
A fixed point in the context of a figure being rotated is a specific point in the plane that remains unchanged during the rotation. This point serves as the center of rotation, around which all other points in the figure move in a circular path. For example, when a triangle is rotated 90 degrees around a fixed point, the position of that point remains constant, while the triangle's vertices change their locations relative to it.
When u rotated a figure 180 is the reflection the same

the answer would be 180 degrease and if you don't believe me go on another website...

It is called a rotation.
For every point A = (x,y) in your figure, a 180 degree counterclockwise rotation about the origin will result in a point A' = (x', y') where: x' = x * cos(180) - y * sin(180) y' = x * sin(180) + y * cos(180) Happy-fun time fact: This is equivalent to using a rotation matrix from Linear Algebra! Because a rotation is an isometry, you only have to rotate each vertex of a polygon, and then connect the respective rotated vertices to get the rotated polygon. You can rotate a closed curve as well, but you must figure out a way to rotate the infinite number of points in the curve. We are able to do this with straight lines above due to the property of isometries, which preserves distances between points.

Additionally, the orientation may change during rotation, but the relative positions of the points remain consistent in translation.
A rotation of 270 degrees counterclockwise is a transformation that turns a figure around a fixed point by 270 degrees in the counterclockwise direction. This rotation can be visualized as a quarter turn in the counterclockwise direction. It is equivalent to rotating the figure three-fourths of a full revolution counterclockwise.
The least angle at which the figure may be rotated to coincide with itself is the angle of symmetry.
