Which shape has no straight side?
Answer and explanation
Correct answer: Circle
A circle is a closed shape whose boundary bends smoothly all the way around. Because its boundary never becomes a straight line, it has no straight side. In elementary art, a side usually means a straight edge of a closed shape. This makes the circle different from shapes made with line segments. The important idea is to look at the outline, not at the space inside it. A curved outline can enclose an area even when it has no straight edges.
The circle is choice A. A square has four straight sides, and a rectangle also has four straight sides, even though their lengths may differ. A triangle has three straight sides. Thus, each of choices B, C, and D includes straight edges, while only the circle has a completely curved boundary. The supplied answer A is correct and matches the basic element-of-art concept of shape. It is therefore suitable for a school-level question.
