Step-by-step explanation:
A two-column proof lists the various statements with their associated reasons. Statements are provided on the left side. The idea is to start with what is given, then use established theorems to build to the statement that you want to prove.
A paragraph proof is written in verbal form (rather than use symbols for instance). This is basically where you use conversational language to convince a friend of some aspect about geometry.
A flow proof, aka flowchart proof, is where you use visual bubbles and arrows to show how one theorem leads to another. It's similar to how a two-column proof builds upon each previous statement.
