Question

Use complete sentences to describe why postulates are helpful?

Answer 1

Answer:

• Postulates are the most important building blocks of geometric proofs.

• Postulates are often the basic truth of a much larger theory or law. Postulates themselves cannot be proven, but since they are usually obviously correct this is not a problem.

• A postulate (also sometimes called an axiom) is a statement that is agreed by everyone to be correct.

     A good example of a postulate is given by Euclid as:

          "  Two points determine (make) a line "

Answer 2

Postulates are helpful because it helps you plan and solve geometry problems.
That's my guess. It doesn't tell me in the text either.
