To estimate the quotient, we first round off the divisor and the dividend to the nearest tens, hundreds, or thousands and then divide the rounded numbers. In a division sum, when the divisor is made up of 2 digits or more than 2 digits, it helps if we first estimate the quotient and then try to find the actual number.
1. It is easier to apply it to real-world situations once you have learned to construct geometric figures using compasses and straightedges.
2. Constructing geometric figures yourself also helps you understand the material and learn easily.
3. There is more accuracy and it is easier to prove your accuracy in your own constructions.
I hope this helps :)
