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.
