Q.

Ted is a very studious guy. And guess what, he loves experiments.One of the fields of Mathematics that particularly interests him is Geometry. But the problem is that he doesn't know the ABC of Geometry. Since you have already understood Geometry, you could help Ted. So today, you aren't a student. You are a teacher! To start with, pick an option which gives the meaning of the word Geometry.

1. Just measurement
2. Measurement of world
3. Measurement of earth
4. Measurement of anything
