List the given statements, and then list the conclusion to be proved. Before beginning a two column proof, start by working backwards from the "prove" or "show" statement. If you derived or estimated the information, explain how you reached your conclusion. Says that If a triangle is an acute triangle, then all of its angles are less than 90 degrees., And, If a triangle is an obtuse triangle, then one of its angles is greater than 180 degrees., States If two lines, rays, segments or planes are perpendicular, then they form right angles (as many as four of them)., States, If an angle is a right angle, then the angle must EQUAL 90 degrees., If an angle is an acute angle, then the angle must be less than 90 degrees., If an angle is an obtuse angle, then the angle must be greater than 90 degrees.. This table can help us use statements to arrive at statements that logically follow. The first way that isn't used that often is called the paragraph proof, the second way is called the two column proof and the third method is called flowchart proofs, so here its really easy to see using a picture your reasons and what your reasons allow you to conclude, so I'm going to show what a typical flowchart proof will look like .
