A direct proof in geometry is a proof where you begin with a true hypothesis and prove that a conclusion is true.
Theorems are statements in geometry that require proof.
I am not really sure what you are asking but there are 3 types of proofs in geometry a flow proof, a 2-collumn proof, and a paragraph proof.
A geometry proof is a step-by-step explanation of the process you took to solve a problem. Instead of using numbers, you use words. There are two types of proofs: a paragraph proof, and a column proof. The column proof is the most common proof. In this proof, you must set up a t-chart. On the left side, you must write the steps you took to solve the problem. Make sure you number each step. On the right side, explain why you took this step. Make sure to number each explanation with the same number as the step on the left side you are explaining. Sources: Calculus III Student in 12th grade Took geometry in 8th grade
