There are two main types of sectors: minor and major!
A minor sector is a small piece of the circle, just like a tiny slice of pizza. ๐
For example, if you take a slice that is less than half the pizza, that's a minor sector. A major sector, however, is larger. If you take more than half the pizza, thatโs a major sector! ๐
Sectors can be measured in degrees, and a whole circle has 360 degrees. So a minor sector might only be, say, 90 degrees, while a major one could be 270 degrees!
