What is the purpose of a proof in Geometry? What is structure of a proof in Geometry?

Geometry (like any other branch of math) starts from a set of statements that we assume to be true, which we call axioms.

Then, we declare some rules that allow us to deduce true things from true things. For example, syllogism is one of this rules. So, if we know that is true, and it is also true that , then we're allowed to deduce that is true as well.

So, the purpose of a proof is to show that a certain statement is true.

In its structure, you'll always start from some true facts, and you'll deduce new true facts by using allowed deductive methods.

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
