Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0). Plot triangles PQR and P'Q'R' on your own coordinate grid. Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R'? Explain your answer. (4 points) Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis. (4 points) Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer. (2 points)

@chris00 thanks I won't be able to complete pressed for time

Other answers:

did you plot the points?
yes
can you guys explain all the answers for me please
to reflect across the y-axis each point (x, y) goes to (-x, y)
congruent means same compare the lengths and angles
do you know how to calculate scale factors @nuccioreggie
scale factor is the ratio of the sides from
no
you can pick any point to determine the scale factor
ok
scale factor = new image/ old image
So for Part A?
P'(1, −2) (new image) old image P(3, −6))
um uhhh i sthat for part A?
you can choose the x or y-coordindate to solve for it
scale factor = 1/3
ok can you explain the answer for part A in 1 comment please
i just did...
ohhhh lol im so sorrry so scale factor = 1/3 is the answer
a) scale factor = new image/old image Pick a point, so P. P is the old image. P' is the new image. to determine the scale factor we can either use the corresponding x co-ordinate or y-coorindates. using the co-ordinates P'(1, −2) (new image) old image P(3, −6)) therefore using x co-orindate scale factor = P'/P = 1/3 or using y co-orindate scale factor = P'/P = -2/-6=1/3 therefore scale factor = 1/3 we can see this seems right because the new image is smaller than the old image
good?
wow lol yea thanks so what about B and C?
yep ok
if we want to reflect it in the y axis, |dw:1444397999471:dw|
as triciall said each point (x, y) goes to (-x, y)
oh ok so what will the answer for letter B will be?
Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0). Therefore, P"Q"R" have verticies P''(-1,-2) Q'' (0,3) R''(1,0)
|dw:1444398231371:dw|
ok soooo i get that the answer for C?
B) since y-reflection means each point (x, y) goes to (-x, y) Therefore, Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0). Therefore, P"Q"R" have verticies P''(-1,-2) Q'' (0,3) R''(1,0)
the diagram is used for C
|dw:1444398545805:dw|
CAN YOU PUT THE ANSWER FOR c in word please?
C) Triangles are congruent when they have exactly the same three sides and exactly the same three angles So no triangles PQR and P''Q''R'' are not congruent
thank you
np
i think i get a fan after that ahah
can you help me with like 2more questions?
sorry, i have to go to sleep. its past midnight >.<
good luck
preciate it
