The word 'triangle' is used to describe a shape that has three sides and three angles. It is commonly found in geometry and can be seen in various objects, such as road signs, pizza slices, and musical instruments. When we talk about triangles, we may refer to different types, such as equilateral (all sides and angles are equal), isosceles (two sides and angles are equal), and scalene (none of the sides or angles are equal). You may come across the word 'triangle' in math class, when reading a book, or even when playing a game.
