An equilateral triangle is a three-sided polygon characterized by three equal-length sides and three equal interior angles, each measuring 60 degrees.
Its defining feature is the uniformity of its sides and angles, creating a perfectly balanced and regular geometric shape. Equilateral triangles exhibit a high degree of symmetry, making them essential in geometry, engineering, and various mathematical applications.
They are often employed in structural design, tessellations, and trigonometric calculations due to their predictable properties. This symmetrical shape plays a fundamental role in understanding geometry, providing a foundation for more complex geometric concepts and constructions.
