C is the point that does not move because it is on the line of reflection
Yes, a reflection is a rigid motion. It does not change size. A dilation changes the size.
Step-by-step explanation:
In the picture, you will see that I traced the triangle on tracing paper and then folded (flipped) the drawing over the line of reflection.

When we rotate a figure and there is no change in the shape of the figure then it has rotational symmetry.
We know that the order of rotation for a square is 4.
Hence, we have
Thus, the angle of rotational symmetry of square are
Hence, the minimum angle of rotational symmetry is
Therefore, the minimum angle of rotational symmetry for a square is 90 degrees.
