line up ABCD and PMNO
|dw:1478490759021:dw|
jimthompson5910 (jim_thompson5910):
notice how BC is over MN|dw:1478490789535:dw|
OpenStudy (mimijola):
I thought so..Thanks!
jimthompson5910 (jim_thompson5910):
so BC corresponds to MN
if ABCD is congruent to PMNO, then that means BC = MN

see attached
where is point A located?
OpenStudy (mimijola):
-4,2?
jimthompson5910 (jim_thompson5910):
I agree with x = -4
but not with y = 2
OpenStudy (mimijola):
I'm not sure wat y is..?

jimthompson5910 (jim_thompson5910):
it's between the y = 0 and y = 2 tickmarks, so I'd say maybe y = 1 is a good guess
jimthompson5910 (jim_thompson5910):
so you agree that A is at (-4,1) ?
OpenStudy (mimijola):
ohhh ok..yes
jimthompson5910 (jim_thompson5910):
where is point B?
OpenStudy (mimijola):
3,1?

you mixed up x and y
use parenthesis to surround the two values
OpenStudy (mimijola):
oh so 1,3
jimthompson5910 (jim_thompson5910):
use parenthesis
(1,3)
OpenStudy (mimijola):
(1,3)
jimthompson5910 (jim_thompson5910):
where is C located?

OpenStudy (mimijola):
(1,1)?
jimthompson5910 (jim_thompson5910):
no
jimthompson5910 (jim_thompson5910):
remember each tick mark is 2
also, C is below the x axis
OpenStudy (mimijola):
Explain please?
jimthompson5910 (jim_thompson5910):
hmm, ok so notice how C is close to the vertical dotted line?
so that means that the x coordinate is probably x = 2

it's not perfect but it's close enough
jimthompson5910 (jim_thompson5910):
hopefully you can see how x = 2?
OpenStudy (mimijola):
I'm confused. I'll do this later but Thanks for your help :)
jimthompson5910 (jim_thompson5910):
no problem
