Things That Are Triangular in Shape

Welcome to our list of things that are triangular in shape! ◢◤△🔻◭

Triangles are three-sided shapes characterized by three points and three sides. They come in various types based on their sides and angles: equilateral (all sides and angles are equal), isosceles (two equal sides and angles), and scalene (no equal sides or angles). As fundamental shapes in geometry, triangles have properties and theorems, such as the Pythagorean theorem for right triangles, that are foundational to various mathematical and real-world applications.
