Yes, triangle B is a rotation of triangle A.
How is it so?
A rotation is a transformation that turns a figure around a fixed point called the center of rotation. The figure is turned around the center by a certain angle, and the distance between each point of the figure and the center remains the same.
Looking at the corresponding sides and angles of the given information, it could be seen that Triangle B has the same shape as Triangle A, but it is rotated.
The corresponding sides of Triangle B align with the corresponding sides of Triangle A in terms of length. Additionally, the corresponding angles of Triangle B align with the corresponding angles of Triangle A.
Therefore, it could be concluded that Triangle B is indeed a rotation of Triangle A.
