Which shape has three corners?

Triangle

A shape’s corners are the points where two straight sides meet. A triangle is a closed, flat shape with exactly three straight sides and three such meeting points, called corners or vertices. Therefore, the shape with three corners is the triangle. Its form may look different when it is turned, stretched, or drawn with unequal sides, but it still has three sides and three vertices. The word “tri” is also useful as a memory clue because it is connected with the idea of three.

The other choices do not fit this description. A circle has a continuous curved boundary and no corners. A rectangle has four sides and four corners. A pentagon has five sides and five corners. Counting the corners of each option shows that only the triangle has three, so option C is correct. The answer does not depend on the triangle’s size, direction, or exact appearance; as long as its three sides meet in three points, it remains a triangle.
