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

OpenStudy (mimijola):

Do you mind helping me with another?

jimthompson5910 (jim_thompson5910):

sure

OpenStudy (mimijola):

One second please

OpenStudy (mimijola):

jimthompson5910 (jim_thompson5910):

do you see where the vertices are located?

OpenStudy (mimijola):

Not sure

jimthompson5910 (jim_thompson5910):

are you able to zoom in on the drawing?

OpenStudy (mimijola):

Yes

jimthompson5910 (jim_thompson5910):

can you show me the zoomed in version?

OpenStudy (mimijola):

ok

OpenStudy (mimijola):

jimthompson5910 (jim_thompson5910):

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?

jimthompson5910 (jim_thompson5910):

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

jimthompson5910 (jim_thompson5910):

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
