Answer:

B. vertical line symmetry
C. diagonal line symmetry
D. rotational symmetry

Step-by-step explanation:

Any line through a vertex and the center of the opposite side is a line of symmetry. One of them is vertical in the figure shown. Two of them are diagonal. The three lines are 360°/3 = 120° apart, so the figure has 3-fold rotational symmetry.
