of these figures can be classified in the same group. Which is the best explanation of Susan's reasoning? Susan used the number of sides to classify the figures because each figure has 4 sides. Susan used the presence of parallel sides to classify the figures because each figure has at least one pair of parallel sides. Susan used the presence of perpendicular sides to classify the figures because each figure has at least one pair of perpendicular sides. Susan used angle measures and symmetry to classify the figures because eac figure has 0 right angles and at least 2 lines of symmetry.
