do you mean find the length of each piece? or actually trisect the segment through a geometric construction?

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
I think to find the length of each piece. The exact questions says: Now that you know how to find the midpoint from two endpoints, tweak your understanding of the formula to uncover a way to divide a line segment in to three equal parts. What would the formula look like?

One way to do it is to divide the horizontal component of the length by 3 this will give you how far to space the points out in a horizontal sense you must do the same for the vertical component as well

so say you had this segment dw:1378786046754:dw

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
draw in the horizontal and vertical components dw:1378786083004:dw
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
then cut those lengths into 3 congruent pieces dw:1378786121773:dw
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
then use these cuts to figure out where the 1/3 and 2/3 markers go on the original line segment dw:1378786176000:dw

yeah, i get what your saying, but there isn't any specific formula where you have to plug in the numbers?

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
well this distance here dw:1378786360035:dw is the difference in the x coordinates
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
this distance is the difference in the y coordinates dw:1378786383951:dw
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so you're subtracting the coordinates, then dividing by 3 to get those markers on the horizontal/vertical components and you're using those markers to get the 1/3 and 2/3 markers

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
but the question is asking me for a formula?
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
I know, I'm trying to get you to think of what that formula would be based on what I'm giving you

how about a+b+c=? divide by 3

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
not quite

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
remember you're taking the differences in the corresponding coordinates, then dividing by 3
 one year ago

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
oh so then instead of adding them, im subtracting them?
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
let m = x2  x1 this is the horizontal component length and let n = y2  y1 this is the vertical component length
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
cut these distances into 3rds: m > m/3 n > n/3 so if you have the segment with the endpoints (x1,y1) and (x2,y2), then you're adding on m/3 to the coordinates to get these points 1/3 marker: (x1 + 1*m/3, y1 + 1*n/3) 2/3 marker: (x1 + 2*m/3, y1 + 2*n/3) you could avoid using m and n and just use the distances above, but that notation gets even uglier

yeah, this looks really complicated lol:p

thanks for helping me tough. i hope the teacher goes over this tommorow because right now i just want to know out!

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
do you see how I defined m and n?
 one year ago

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
Yeah, yes I did:)
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so if you cut m into 3 then you basically get this distance here dw:1378787464289:dw
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
and if you divide n by 3, you get this length here dw:1378787503944:dw

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
with me so far?
 one year ago

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
yes, with you so far:)
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so that's why if you start with (x1,y1) dw:1378787643610:dw
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
and you move m/3 units along the x axis and n/3 units along the y axis, then you'll land at the 1/3 marker dw:1378787687368:dw
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
that explains why the coordinate of the 1/3 marker is (x1 + m/3, y1 + n/3) and you can write it as (x1 + 1*m/3, y1 + 1*n/3)
 one year ago

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
thank you so much i appreciate it:)
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
you're welcome, the 2/3 mark is found in much the same way, you add on another m/3 to the x coordinate and another n/3 to the y coordinate to get 2/3 marker: (x1 + m/3+m/3, y1 + n/3+n/3) which turns into 2/3 marker: (x1 + 2*m/3, y1 + 2*n/3)
