Explore Sulbasutra square construction
Understand the idea behind constructing a square with a given side.
4
Understand basic objects
Describe undefined geometric ideas using intuitive language.
5
Definition, axiom or postulate?
Classify mathematical statements by their role in reasoning.
6
Know Euclid’s postulates
Recall and explain the basic assumptions used in Euclidean geometry.
7
Compare geometric measures
Apply common notions such as equality and addition of equals.
8
Understand parallelism
Explain what it means for two lines in a plane not to meet.
9
Use axioms to justify
