marry me :DDD
OpenStudy (anonymous):
well that was not what i was expecting
jimthompson5910 (jim_thompson5910):
yeah a bit creepy, anyways, a parallelogram is a quadrilateral with 2 opposite sides parallel
jimthompson5910 (jim_thompson5910):
this means
BC || DE
and
CD || BE

let me know if that's enough to get started
OpenStudy (anonymous):
so positive p for the first letter?
OpenStudy (anonymous):
or would it be r,q
jimthompson5910 (jim_thompson5910):
notice how point D is completely on the same horizontal level as point C
jimthompson5910 (jim_thompson5910):
therefore, point D and point C must have the same y coordinate

q is going to go in the y coordinate slot for the answer
jimthompson5910 (jim_thompson5910):
the x coordinate is a bit tricky

|dw:1416356830454:dw|
jimthompson5910 (jim_thompson5910):
|dw:1416356843237:dw|
jimthompson5910 (jim_thompson5910):
let's start at point B and go to point C
how do we do that? we go to the left p units and go up q units

jimthompson5910 (jim_thompson5910):
we follow the same pattern going from E to D
start at (r,0) and go left p units to get to (r-p,0)
then go up q units to get to (r-p,q)
jimthompson5910 (jim_thompson5910):
|dw:1416356989790:dw|
jimthompson5910 (jim_thompson5910):
so point D is the point (r-p, q)
OpenStudy (anonymous):
that is confusing but i think i understand
jimthompson5910 (jim_thompson5910):
yeah it's probably more confusing because of all the letters

try replacing the letters with numbers and see if that helps
OpenStudy (anonymous):
that'll probably help. thank you (:
jimthompson5910 (jim_thompson5910):
you're welcome
