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.

1st it seems to be NePAL'S flag!! hehe ;)
Does anyone know how to do this..?
what i think is.... findthe lengths of each sides of the 2 triangles .. and then compare the two triangles!!
Could you help me to do that?
I just need the answer because I don't know how to set it up.

c dis is d triangle!!
U KNOW THE DISTANCE FORMULA RIGHT?
Yes, I do, but I was wondering if the two triangles were congruent, similiar, or neither? It looks like neither.
ok..now calculate the sides ...by using distance fomula!!
and then compae get it?
No, I'm still lost.
When you get the distance, you can compare them Same length of side pairs=> congruent Length are in ratio => similar Neither => neither
ok first u calculate the distances ..and then temme!!
@Callisto .....hell yeah!
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??
So what would the answer be?
I've typed that about 10 minutes ago :|
u try it urslf.. callisto has given u hint
You need to find out all the length first :|
I don't understand how. ):
c dis ... u'll undrstnd http://www.teacherschoice.com.au/maths_library/trigonometry/triangle_given_3_points.htm
Ok, I will work it out.
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?
are u doing your home work her??
I am taking questions from a review and trying to figure them out.
I don't know what it is asking for. If the two triangles are congruent, they equal each other.
see.. if two triangles ar congruent means .. there all sides are equal.. and allangles are equal!!
So on a graph, it would be on the opposite side of the first?
not necessary ... but yes eevn that is a possibility ..
there are many possibilities
A(2,6) B(2,4) C(4,3) Is this congruent to the first?
best method to find answers for such question is ... add or subtract a constant to all the coordinates!!
wcum ..srry 4 dis... bt medal!!
