How many sides does a triangle usually have?
Answer and explanation
Correct answer: Three
A triangle is a closed plane shape made from three straight line segments. Each segment is called a side. The sides meet in pairs at three corner points, called vertices, and these corners form the triangle’s angles. The number of sides is part of the definition, so it does not depend on whether the triangle is small, large, narrow, or wide.
Therefore option B, three, is correct. A shape with two sides cannot enclose an ordinary polygonal region, while a four-sided shape is a quadrilateral and a five-sided shape is a pentagon. The word “triangle” itself refers to a figure with three angles, and the corresponding three sides form its boundary. Thus the usual elementary definition directly leads to the answer.
