The chart below describes three triangles. Name of triangles Description Triangle ABC and triangle CFD Similar triangles Triangle ABC and triangle DCE Congruent triangles Triangle CDE and triangle CFG Similar triangles Part A: Write the coordinates of points A, B, C, D, E, F, and G. Part B: Using complete sentences, prove that the coordinates chosen for the points are correct.
PLease HELP ME!!!
Someone HELP!
or tag somone who can help
HELP!!!!!!!!!!! im so tired
@Callisto or @Hero haha I don't know who on here is good at geometry, no one seems to like it much xD
Help
Any missing information?!
No... its just a table and i posted it up already
coordinates of points A, B, C .... ?! Do you mean that you can simply... make up the numbers?
yes
but they have to make sense :)
Alright... Then.... Since every triangle includes a point C. Pick C = (0, 0)
(Just for convenience) Pick some points for A and B... It's easier if A, B, and C form a right angle triangle.
like which ones
Like this.
go on.. ;) and thank you
Now, for the first condition, Triangle ABC and triangle CFD -> Similar triangles Angle BAC = Angle FCD Angle ABC = Angle CFD Angle ACB = Angle CDF Now, wisely pick some coordinates for D and F. Don't worry, I won't do it for you.
so how about 0,2 and 1.5,0?
since its proportional
Then, it would be a triangle inside triangle ABC Wait...Are you sure triangle ABC and triangle CFD are similar triangles (be careful of the angles...)
a(0,4) b(2,0) c(0,0) d(-4,0) e(0,8) f(0,2) g(4,0)
Boom ;p
replace e and f
Sorry, this one. What do you mean for 'replace e and f' ?
everyone wins
