You can use parallel lines to compare figures Q and R by observing if corresponding sides are parallel, which helps determine if the figures are similar. Which of the following best explains how parallel lines can be used to compare figures Q and R?

• By checking if corresponding sides are parallel to determine similarity.

• By measuring the area of both figures.

• By comparing the color of the figures.

• By counting the number of angles in each figure.
