Question

1. which figures represent a pair of similar figures? a. a and b b. a and c c. c and d d. b and d

Explanation:

Step1: Recall similarity criteria

Similar figures have proportional side - lengths and equal corresponding angles.

Step2: Analyze side - length ratios

For trapezoids in figures A and C, we can observe that the ratios of their corresponding side - lengths are equal. For example, if we consider the vertical and horizontal side - lengths of the non - parallel sides and the bases, the ratios are consistent. Also, the angles in trapezoids A and C are equal.

Answer:

B. A and C
