subtract 30 from 180
if i am reading it right it is it does say the lines are parallel right?
then yeah , that's it
how'd u get 30 for the other one?
idk what the name of that is lines are parallel so angles are the same
it is more or less obvious right?
gotcha and ye obvious...;p can u help with 2 more ? ;p pleeeaase
lol i can try i pretty much suck at geometry
but if they are like this, then no problem
omg same xD i hate how this one is labeled....:/ http://prntscr.com/80z9yv
they arent like the one we did :/
3 , 2, 8, 6 are congruent as before right?
Those would all be congruent to angel 1 right?
not sure what the first question is asking 1 and 2 are "supplementary" as they add up to 180
no, they need not be congruent to angle 1 all you are given is R and S are parallel
here is an exaggerated picture |dw:1438744283788:dw|
you see that it is not given that the other two lines are perpendicular to R and S even though it looks like it in the picture so 1 and 2 need not be congruent
i hate geometry -.- this is confusing :/ but its asking for angel pairs.... :/
right so lets go slow (since i will have to look this up)
1 and 2 are supplementary
since they add up to 180
1 and 3 are supplementary as well, for the same reason
1 and 4 are congruent
i will leave it up to you to compare to 5, 6, 7 8 but it is the same as above
so 1 n 5 1 n 6 1 n 7 1 n 8 ?
everything with ones right? ;p
yeah looks like you have to compare all with 1
two will be congruent, which seems to be the geometry word for equal and two will be supplementary
huh? :/ wait for b. i just compare on will 3 so similar to 1 right...?
b just says name the angles congruent with 3
i think the property is called "alternate interior angles" or sommat the ones that are congruent with 3 should be fairly obvious
Got it thanks sat :) hope u aren't the creator of geometry =.= ;)
hell no now i have a question who is in your picture?
I hated these too when I studied this last semester. It's everywhere in Euclidean Geometry -_-
that iz i ^-^ i iz flawless :)
why so shocked ;p ? yeee its me :)
haha thanks :)
