whats the question?
those are the questions

they should be able to help you :) @gar2d2
I don't know how to Explain how to do proofs, sorry :(
@AccessDenied
AB=AD (given) CA=EA (given) <CAB=<EAD (vertically opposite angles ) Hence triangle ABC=triangle ADE (SAS=SAS)
NOTE = MEANS congruent to. i don't know how to write it.
<BCD=<EDC (given) <BDC=<ECD (given) CD=CD (common) Triangle BCD=Triangle EDC (sss=sss)
thanks suriji this is really awful stuff i didnt expect geometry to have anything to do with things like this i thought it was going to be mainly area and measurements and stuff, but postulates and theorems really has me confused,
i really dont understand this , proof makes me want to kill myself
u still confuse in it ?
ill help u step by step in this geometry , but dnt kill ur self lol
yes i dont know what properties definitions or theorems are needed to solve these bad boys they are ruining me i am going crazy maybe im not trying hard enough i just wanta simple wayof looking at the figure and knowing what to do but it asks me so many steps i dont know exactly what im looking for
1. Given: AB=AD CA=EA Prove: triangle ABC= triangle ADE |dw:1395268427803:dw|
lets start with this question ok ? do u know what does congruent means ?
yes it means they are equal
ok then when two triangels are congruent ?
so dealing with these we are finding out why these figures are congruent? when they are both congruent they are the same
yess correct ! now there is 4 kind of congruent SSS ( side, side , side) SAS ( side , angle , side) ASA( angle ,side, angle) SSA ( only for right angels ) ok ?
nw u need to find if these two triangle are congruent lets see ur given AB=AD CA=EA ok ? |dw:1395268898538:dw|
got this ?
yes adn they share the same angle a
so that would mean that it is sas
but what if the figure is like the figure in #5
wow this is kinda getting like clearer but the figures are really confusing sometimes
they dnt share the angle we say that < CAB=< DAE couse they are VERTICALS angles |dw:1395269029581:dw|
