Which one of the following has four sides?
Correct answer: B. Square
- A. Triangle
- B. Square
- C. Circle
- D. Right triangle
Explanation
A triangle has 3 sides as "tri" is in the name which means 3. A right-angled triangle also has 3 sides. A circle has no sides as a side requires two distinct end-points joined by a straight line. For a circle, this will never be the case. A square has 4 corners hence it has 4 sides.
