Write proof initials

in this video we're going to go over two column proofs with segments or basically you can say segment proofs so let's say we have this segment with the points a b c and d and we're given that segment a b is congruent to segment cd our task is to prove that segment ac is congruent to segment bd go ahead and try that so let's create two columns we're going to put the statements in the first column and then the reasons for those statements in the second column now the first thing we should write as our statement is what's given that is segment a b is congruent to segment cd and that's a given now what's the next step that we can do the next step is sort of a formality if segment a b is congruent to segment cd then mathematically speaking we can say that a b is equal to cd now what's the reason for this what can we put in the second column for this situation you can say definition of congruent segments so i'm not going to write the whole sentence out just to conserve space but you get the point now let's move on to number three so let's talk about what we're trying to do we're trying to prove that ac which is this part is congruent to bd we know that a b is equal to cd so the only part that's missing is bc notice that a b plus bc will give us segment ac and bc plus bd will give us i mean bc plus cd will give us bd so this tells us that we need to add bc to both sides of this equation but before we do that let's write down another formality we're going to say that bc is equal to bc based on the reflexive property now you might be wondering why do we need to do that some teachers may require it others may not but just in case we're gonna put that there so now we're gonna add statements two and three the equations for it so we're gonna get a b plus bc basically add in the left side and add in the right side of the two equations we're going to get that's going to equal bc plus cd now this is basically the addition property of equality i'm just going to write addition now let's move on to step five so what is a b plus bc equal to so as we said before a b plus bc is ac so let's make that our statement for number five a b plus bc is equal to ac and focusing on the right side of the equation bc plus cd that's going to be bd so let's write that as one bc plus cd is equal to bd so what should we write on the right side for this this is the segment addition postulate so i'm...
