Carla drew two triangles; triangle ABC and triangle PQR, on a grid. She planned to cut out the two triangles to make a flag. The vertices of triangle ABC are at A(1, 4), B(-2, -1), and C(3, -2). The vertices of triangle PQR are at P(-3, 0), Q(-2, -4), and R(2, 3). Using the coordinates of the vertices of each triangle explain whether the two triangles are congruent, similar or neither. Note: I understand I have to apply the formula, but I don't know what goes into it. Help is appreciated.

Does anyone know how to do this..?
anonymous
  • anonymous
what i think is.... findthe lengths of each sides of the 2 triangles .. and then compare the two triangles!!
anonymous
  • anonymous
Could you help me to do that?

c dis is d triangle!!
anonymous
  • anonymous
U KNOW THE DISTANCE FORMULA RIGHT?
anonymous
  • anonymous
Yes, I do, but I was wondering if the two triangles were congruent, similiar, or neither? It looks like neither.
anonymous
  • anonymous
ok..now calculate the sides ...by using distance fomula!!
anonymous
  • anonymous
and then compae get it?
anonymous
  • anonymous
No, I'm still lost.
anonymous
  • anonymous
*compare
Callisto
  • Callisto
When you get the distance, you can compare them Same length of side pairs=> congruent Length are in ratio => similar Neither => neither
anonymous
  • anonymous
ok first u calculate the distances ..and then temme!!
anonymous
  • anonymous
@Callisto .....hell yeah!
anonymous
  • anonymous
Can someone show me how to get the distance? I know the formula, but not what to plug in.

\[AB=\sqrt{(1-(-2))^2 + (4-(-1))^2} = \sqrt{(3)^2 + (5)^2} = \sqrt{34}\]

c callisti did it already... @Callisto how r u so fast in latex??
anonymous
  • anonymous
So what would the answer be?
Callisto
  • Callisto
I've typed that about 10 minutes ago :|
anonymous
  • anonymous
u try it urslf.. callisto has given u hint
Callisto
  • Callisto
You need to find out all the length first :|
anonymous
  • anonymous
I don't understand how. ):
anonymous
  • anonymous
ooo ...lol
anonymous

Hahaha.

c dis ... u'll undrstnd http://www.teacherschoice.com.au/maths_library/trigonometry/triangle_given_3_points.htm
anonymous
  • anonymous
Ok, I will work it out.
anonymous
  • anonymous
its an example!!
anonymous
  • anonymous
It is neither?
Callisto
  • Callisto
I think so
anonymous

Yay!

The vertices of triangle PQR on a coordinate grid are P(1, 5), Q(1, 3), and R(3, 2). Provide the coordinates of the vertices A, B, and C of triangle ABC that is congruent to PQR and explain why the two triangles are congruent. Do you understand this?
anonymous
  • anonymous
are u doing your home work her??
anonymous
  • anonymous
c'mon do it!!
anonymous
  • anonymous
I am taking questions from a review and trying to figure them out.
anonymous
  • anonymous
I don't know what it is asking for. If the two triangles are congruent, they equal each other.
anonymous
  • anonymous
see.. if two triangles ar congruent means .. there all sides are equal.. and allangles are equal!!
anonymous
  • anonymous
So on a graph, it would be on the opposite side of the first?
anonymous
  • anonymous
not necessary ... but yes eevn that is a possibility ..
anonymous
  • anonymous
there are many possibilities
anonymous
  • anonymous
A(2,6) B(2,4) C(4,3) Is this congruent to the first?
anonymous
  • anonymous
yep
anonymous
  • anonymous
best method to find answers for such question is ... add or subtract a constant to all the coordinates!!
anonymous
  • anonymous
TY
