Final answer:
To identify lines that are perpendicular, we look for those forming a 90° angle. Based on the given options, 'b' and 'd' suggest perpendicularity. For accurate identification, however, a diagram or context for the lines K, M, P, Q, and S is necessary.Options b and d indicate perpendicularity directly.
Step-by-step explanation:
To identify all pairs of lines that appear to be perpendicular, we look for line pairs that meet at a right angle, which is 90 degrees. From the information given, we can determine:
b. They are perpendicular, forming a 90° angle between each other.
d. They are perpendicular, forming a 270° angle between each other. While a 270° angle implies a 'three-quarters' turn, the actual perpendicular relationship occurs at 90°, which is a quarter turn from the start and is congruent to 270° in terms of perpendicularity.
Options b and d indicate perpendicularity directly. However, for a complete understanding of the question, we would need a visual representation or a clear description of the arrangement of lines K, M, P, Q, and S. As we lack this context, we can only assume that options b and d are valid answers to the question. Please note that it's critical to check these line pairs on a diagram or within their specific context to confirm their perpendicular nature.
