# Triangles - Basics and Theorems

Triangles are polygons with least number of sides, i.e three. Interestingly you can divide any complex polygon into several triangles. This method is often used to calculate the area of a complex polygon by breaking it into triangles, thus reducing the complexity of calculation. Watch our videos to learn more about triangle, right-angled triangle, isosceles triangle, congruent triangle, and other astonishing concepts related to them.
