momo · Answer

i thought it could be AA or SAS

momo · Answer

i was leaning more towards AA

anonymous · Answer

what is SAS and AA and SSS?

amistre64 · Answer

AA is my guess; your got 2 angles the same; but i dunno how much proof that is

momo · Answer

i was guessing AA also because the sides are smaller

amistre64 · Answer

the crossin glines tells you the angle interior is the same; and the measure of that outside one thats marked is the same...

momo · Answer

yeah, so i'm going with AA
lol

momo · Answer

so are you a math teacher?

amistre64 · Answer

going for my masters in math to be a college math teacher...so maybe lol

anonymous · Answer

um, it is AAA because it is given that angle ABC is equal to angle ADE

amistre64 · Answer

with 2 angles the same; the third is a given i believe

anonymous · Answer

angle BAC is angle BAE

anonymous · Answer

sorry i meant angle BAC is the same as angle DAE

momo · Answer

ha well you are pretty close. good job :)

anonymous · Answer

so it follows that angle AEB is angle ACB since we know sum of internal angles of triangle is 180.
so we have AAA congruence or whatever they call it. i did all this a long long time ago :)
