Given: Quadrilateral ABCD is a parallelogram
Prove AB is congruent to CD and BC is congruent to AD
Edit: got step 7 guys, its Triangle ABC is congruent to CDA (C, if i remember correctly) Will be back with step 2 answer.
EDIT 2: Got it guys step two is ABllCD and BCllAD and the reason is definition of a parrelelogram i hope tihs helps you'll prolly see this when its a year old lol bet money

Best ResponseYou've already chosen the best response.1okay there are some basic triangle theorems you have to know 3 main ones are AAS, SSS, and SAS theorems that if satisfied means the 2 triangles are congruent

Best ResponseYou've already chosen the best response.1the next is parallel lines and which angles are equal lets start there!

Best ResponseYou've already chosen the best response.1Lets first draw 2 parallel lines and see if we can find something about an intersection of a line through them

Best ResponseYou've already chosen the best response.1oky we know that angle 1 = angle 2 , as these are opposite angles and opposite angles have ot be equal

Best ResponseYou've already chosen the best response.1we can see this very easily as angles along a straight line add up to 180

Best ResponseYou've already chosen the best response.0supplementary, right?

Best ResponseYou've already chosen the best response.1you see how that angle in between 1 and 2, is 180  angle 2 or 180  angle 1

Best ResponseYou've already chosen the best response.1this means angle 2 and 1 have to be the same

Best ResponseYou've already chosen the best response.1tell me if you understand that

Best ResponseYou've already chosen the best response.1okay now you know why opposite angles are equal, lets move on

Best ResponseYou've already chosen the best response.1im not sure exactly how to prove that one, but take that as face value its more intuitive, it must be true kinda thing

Best ResponseYou've already chosen the best response.1like think about it it angle 3 is not the same as angle 1

Best ResponseYou've already chosen the best response.1then these lines cannot be parallel right

Best ResponseYou've already chosen the best response.1these angles have to be the same here

Best ResponseYou've already chosen the best response.1yep that is right, now what does that mean about the remaining angle

Best ResponseYou've already chosen the best response.0and since theres 2 in the parrelelogram its 360 degrees

Best ResponseYou've already chosen the best response.1okay now u see both triangles in there have an angle that is a and angle that is b

Best ResponseYou've already chosen the best response.1what is the remaining angle?

dan815

Best ResponseYou've already chosen the best response.1the remaining angles have to be equal too... tell me why

anonymous

Best ResponseYou've already chosen the best response.0because of the alternate exterior?

Best ResponseYou've already chosen the best response.1we know all the angles add upto 180 right

dan815

Best ResponseYou've already chosen the best response.1a+b+the remaining angle is 180

dan815

Best ResponseYou've already chosen the best response.1then the same remaining angle must be on the bottom too as there is an a and a b

dan815

Best ResponseYou've already chosen the best response.1so we have 3 samme angles and a side that is the same, as the diagonal is shared

dan815

Best ResponseYou've already chosen the best response.1so by AAS rule, these triangles are congruent
