OpenStudy (sleepyhead314):

correct ;P then... gimme a sec to think about the other question .-.

OpenStudy (anonymous):

ok and thanks

OpenStudy (sleepyhead314):

well I've states a couple of rules for you so far in a parallelogram: - the opposite sides are equal to each other (congruent) - the opposite angles are equal to each other so that rules out two of the options then... if one pair of sides are equal and parallel then that makes the same effect as having both opposite sides equal

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

so how do i attack this problem

OpenStudy (sleepyhead314):

process of elimination :P I just told you all the rules that makes a parallelogram

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

is it B

OpenStudy (sleepyhead314):

if one pair of sides are equal and parallel then that makes the same effect as having both opposite sides equal close but not quite ;)

OpenStudy (anonymous):

so its A

OpenStudy (sleepyhead314):

correct :)

OpenStudy (anonymous):
