The complete question is added as an attachment
The coordinates of the triangles are given as:
BCDE has points (2, 1), (2, 4), (4, 4), (4, 1).
B'C'D'E' has points (-1, 2), (-4, 2), (-4, 4), (-1, 4).
From the figure, we can see that the rectangle BCDE is rotated to get the rectangle B'C'D'E'
This rotation is done through the point P as a center of rotation
Hence, the point P is called the center of rotation
