Circle is to Round as Triangle is to ?

Circle is to Round as Triangle is to ?

• A. Circular
• B. Triangular
• C. Square
• D. Flat

Answer: (B)

Think of how a noun for a shape pairs with a word that describes that shape. A circle is a round shape, so the descriptor that fits the circle is round. For a triangle, the shape is described by the word triangular. So the best completion is triangular because it is the standard adjective that describes a triangle’s shape. The other options don’t fit the same pattern: circular describes circles, not triangles; square is a different shape; flat describes depth, not the shape itself.
