Provide the ordered pairs for two congruent triangles on the coordinate plane. Explain, using complete sentences, how you know these triangles are congruent. Provide the ordered pairs for two similar triangles on the coordinate plane. Explain, using complete sentences, how you know these triangles are similar. Provide the ordered pairs for two triangles that have no relationship on the coordinate plane. Explain, using complete sentences, how you know these triangles have no relationship.

Did you draw two congruent triangles?

  • anonymous
no, was i supposed too?
Mertsj
  • Mertsj
The very first thing says to provide the ordered pairs for two congruent triangles. If you don't draw two congruent triangles on a piece of graph paper, how are you going to provide the ordered pairs?

true, im sorry one second i will.
anonymous
  • anonymous
ok i did. now what?
Mertsj
  • Mertsj
Do you have the ordered pairs?
anonymous
  • anonymous
yes. i have 2 triangles ABC and DEF. the orddered pairs for ABC are A=2,1 B= 2,4 and C= 5,1. DEF= D=-2,1 E=-2,4 and F= -5, 1

Now find the lengths of the sides and show that they are the same. That will prove the triangles are congruent.

  • anonymous
how do i find the length of the diagonal?
Mertsj
  • Mertsj
Do you know the distance formula?
anonymous
  • anonymous
ithink so. sqrt of x1-x2+ y1-y2
Mertsj
  • Mertsj
yes
Mertsj
  • Mertsj
Use it to find the lengths of the sides.
anonymous
  • anonymous
ok. so i understand 1 but now 2 im confused about.
Mertsj
  • Mertsj
You mean the similar triangles?
anonymous
  • anonymous
yes.
Mertsj
  • Mertsj
Similar triangles have the same shape but not the same size. Use these ordered pairs: (06) (0,0) and (6,0) for one of the triangles.
Mertsj
  • Mertsj
For the smaller triangle use these ordered pairs: (0,0) (-3,0) and (0,-3)

ok thanks i wil and for the ones that have compleately opposite can i use like big numbers that dont even fit on the grid?
Mertsj
  • Mertsj
Then show that you can multiply the lengths of the sides of the small triangle by 2 to get the lengths of the sides of the big triangle.
anonymous
  • anonymous
ok i see
Mertsj
  • Mertsj
I don't know what that means... the ones that have completely opposite
anonymous
  • anonymous
like say i did 9878,6785 7586,4657 and 1234,3212 for one..i mean the teacher wouldnt even look at them because they are so big of numbers so she knows they have no relationship.?

|dw:1326926228654:dw|
Mertsj
  • Mertsj
No. Do something like (0,0) (0,5) and (7,0) for one triangle and for the other one do (-6,3) (-1,1) and (-3,-5)
anonymous
  • anonymous
ok THANKS!!!!!!!!!1 you have been sooooooooooooooo much help!!!!
