Show the answer and the worked solution
Correct answer: C. Circle
Worked solution
- Triangle, square and rectangle are polygons with straight sides and vertices.
- A circle has neither.
Answer: Circle.
The idea
Ask what property three share that the fourth lacks. Here it is having straight edges and corners.
Shortcut. Count the sides: 3, 4, 0, 4 — the circle alone has no straight sides or corners.
Common trap. "Triangle" — the only three-sided figure beside two four-sided ones, but the circle differs from all three by having no sides at all.
