Which two-dimensional figure has two distinct pairs of adjacent equal sides?

• A. Triangle
• B. Parallelogram
• C. Kite
• D. Pentagon

Answer: (C)

Two adjacent equal-sides in two separate places around the figure define a kite. In a kite, two sides that meet at one vertex are equal in length, and the two sides that meet at the opposite vertex are equal as well. That creates two distinct pairs of adjacent equal sides, exactly what this item describes.

Other shapes don’t fit that pattern. A triangle has only three sides, so you don’t get two separate adjacent pairs around a closed four-sided figure. A parallelogram has equal opposite sides, not adjacent ones, unless you go into special cases where all sides become equal (a rhombus or square), which changes the description. A pentagon isn’t defined by having two such adjacent equal pairs. So the kite best matches the requirement.
