Do you know what are corresponding and alternate angles between parallel lines ?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

im homeschooled and to learn we have to self learn and im not understanding anything.

hartnn (hartnn):

then this might be helpful, have a look http://www.mathsisfun.com/geometry/corresponding-angles.html

OpenStudy (anonymous):

ok

hartnn (hartnn):

could you find x now ? x is corresponding to which angle ?

OpenStudy (anonymous):

i dont know :/

OpenStudy (anonymous):

I have 12 exams to do im only on my third on i got to have them done before august im stressing out because im probably going to fail....i jjust suck at this stuff and on top of that im so stressed im crying over stupid math like usual. math is evil...

hartnn (hartnn):

if you practice, is easy :) now see, |dw:1397719711181:dw| a and b are corresponding angles, do you see a pair of corresponding angles in your diagram ?

hartnn (hartnn):

how about 54 and x ?

OpenStudy (anonymous):

yeah but how do you show your work that that is a pair of corresponding angleS?

hartnn (hartnn):

you don't need to show that, its implicit. just say that since x and 54 degree angle are corresponding angles, they are equal. so, x = 54

OpenStudy (anonymous):

oh..ok. so would that mean that y is 46 degrees?

hartnn (hartnn):

yes, but y= 46 , because they are ALTERNATE INTERIOR angles.

hartnn (hartnn):

|dw:1397719968729:dw| c and d are alternate interior angles, hence c = d
