Which shape has three sides?

Which shape has three sides?

• A. Quadrilateral
• B. Triangle
• C. Hexagon
• D. Pentagon

Answer: (B)

The shape that has three sides is a triangle. Triangles are defined by having three straight edges and three vertices. Each vertex is where two sides meet. The simplicity of a triangle makes it a fundamental shape in geometry, serving as a building block for more complex figures. In contrast, a quadrilateral is defined as having four sides, a hexagon has six sides, and a pentagon has five sides. Each of these shapes contributes to the broader category of polygons but varies in the number of sides, which distinguishes them from a triangle. Understanding these distinctions is essential in grasping geometric principles and classification of shapes.
