Question

what is the first step in determining if two figures are similar? a. compare the ratios of corresponding sides b. reflect one of the figures c. rotate one of the figures d. compare the areas

Explanation:

To determine if two figures are similar, the fundamental step is to check the proportionality of their corresponding sides. Reflecting or rotating figures (options b and c) are transformations and not the first - step for similarity determination. Comparing areas (option d) is not the initial check as similar figures have proportional side - lengths first and then a related ratio of areas.

Answer:

a. Compare the ratios of corresponding sides
