A triangle is defined as a geometric shape that has three sides and three angles. The term "triangle" itself comes from the Latin word "triangulus," which means "three-cornered." Therefore, irrespective of how many sides may be mistakenly attributed to it, a triangle can only have three sides based on its fundamental geometric definition.

This principle highlights the importance of understanding basic geometry when assessing shapes and their properties. While the other choices suggest incorrect numbers of sides, they do not align with the established definition of a triangle. Recognizing this distinction is essential in fields such as mathematics and engineering, where accuracy in terminology is critical.
