Geometry is a large topic that one can relate to practically by visualizing each concept.
 
We can say that each one visible mathematical things that we understand are often categorized under geometry.
The English word "geometry" is the equivalent of the Greek word "Geometron". The words "geo" and "metron" stand for "Earth" and "Measurement," respectively.
We have seen numerous historical monuments, and these monuments have certain shapes and figures which amaze us.
 
Are they very complex structured?
 
No, they're just made by assembling shapes that we learn within the branch of mathematics called “Geometry”.
