Best ResponseYou've already chosen the best response.0i believe that the answer is B , but that is just because i looked at the graph. its like an overlapping reflection, correct? i need help, i need someone to walk me through this . is there like, a formula? the lesson shows me this formula but its not clear on how to use it. \[\sqrt{(y1y2)^2+ (x1x2)^2}\]

Best ResponseYou've already chosen the best response.1that formula you have typed out, do you know what it's for?

Best ResponseYou've already chosen the best response.0@baru i THINK its to find the distance between two points, the lesson doesnt get detailed in it though :( they just start using it through examples

Best ResponseYou've already chosen the best response.1you are right, its for the distance between two points. for two triangles to be congruent, the sides of the triangles should have equal lengths

Best ResponseYou've already chosen the best response.1if you say triangle ABC congruent to DEF it means AB=DE BC=EF AC=DF

anonymous

Best ResponseYou've already chosen the best response.0so how would i calculate f using the formula? would i use the distance between BC or Ac to find F or?...

baru

Best ResponseYou've already chosen the best response.1yeah..that would be the right way, but rather than solve for the coordinates of F, you are given several options for F, just substitute them and find EF and DF, see which one is equal to BC,AC

Best ResponseYou've already chosen the best response.0so i use my options for F? and place them in the formula? im sorry if i dont quite understand, im a slow thinker in the morning :(

Best ResponseYou've already chosen the best response.1find the lengths EF and DF for each of the options, compare with the lengths AC and BC

Best ResponseYou've already chosen the best response.0but how will i know it is right?

anonymous

Best ResponseYou've already chosen the best response.0oh wait i THINK i understand, if they have the same result as the sides of the congruent triangle thats already there (abs) ?

baru

Best ResponseYou've already chosen the best response.1you have to do it for each option. only one option will give you EF=AC and DF=BC (you have to find lengths AC and BC as well)

anonymous

Best ResponseYou've already chosen the best response.0so i go all around? ok so first i find EF=AC right?

baru

Best ResponseYou've already chosen the best response.1first calculate AC and BC and write it down. then find EF for each option, see which one matches the value for AC that you just wrote down

anonymous

Best ResponseYou've already chosen the best response.0ok let me find AC and BC first

Best ResponseYou've already chosen the best response.0@baru can you help me place the points into the formula? A = (1,1) C= (2,3) B= (1,2) C= (2,3)

Best ResponseYou've already chosen the best response.1\[BC = \sqrt{(12)^2 + (23)^2}\]

Best ResponseYou've already chosen the best response.0@baru but how did you place them? like which value was x1 x2 and y1 y2 ?

baru

Best ResponseYou've already chosen the best response.1oh...ok. wait. neglect what i typed just above, i have reversed the formula you gave(but it doesn't really matter). ill type it in detail, wait

Best ResponseYou've already chosen the best response.1umm... how did you get A=(1,1) ??

Best ResponseYou've already chosen the best response.0i looked at the graph to see where the point is, did i saw it wrong? omg let me see haha

baru

Best ResponseYou've already chosen the best response.1so if you want to find the length AC then think of A =(x1,y1) and C=(x2,y2)

baru

Best ResponseYou've already chosen the best response.1so, x1=1 and y1=0 x2=2 and y2=3

Best ResponseYou've already chosen the best response.0or is everything supoosed to stay in the sqr root ?

anonymous

Best ResponseYou've already chosen the best response.0so its supposed to be the sqr root of 10?

baru

Best ResponseYou've already chosen the best response.1yep, AC is square root of 10.

baru

Best ResponseYou've already chosen the best response.1not necessary, option 2 is the only one which gives you EF= square root of 10

baru

Best ResponseYou've already chosen the best response.1did you try finding EF for all the options?

baru

Best ResponseYou've already chosen the best response.1we established that for the two triangles to be congruent, length AC = length DF

baru
 one year ago
Best ResponseYou've already chosen the best response.1you have found that the length AC is square root of ten. the question gives you several options for the coordinates of F. so find the length DF for each of the options, and see which one gives you square root of 10

anonymous

Best ResponseYou've already chosen the best response.0ohhhhhhhhhhhhhhhhhhhhhh ok ok ok so i can test B and see if it gives me squeare rot of 10? and if it does it means that my answer is correct? but if it isnt i keep testing the other options until it matches square root of 10?

baru

Best ResponseYou've already chosen the best response.1what do you mean "so i can test B' ?

baru

Best ResponseYou've already chosen the best response.1oh..lol. Yep, you are absolutely right then

Best ResponseYou've already chosen the best response.0@baru i got the square root of ten aswell!~ does this mean B is my answer? :)
