Answer 1

can anyone please help? :o

Answer 2

C can be crossed out since the shapes will be the same size.

Answer 3

ok.. so we can get rid of that answer choice then.

Answer 4

Can you choose more than one?

Answer 5

yes

Answer 6

Okay so A, B and D is your answer :)

Answer 7

alrighty thank you very much! :D

Answer 8

not c

Answer 10

i would love to help ...

Answer 11

someone has already answered the previous question, but ill go ahead and copy paste the next one.

Answer 12

coolio

Answer 13

Trapezoid PQRS is similar to trapezoid PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

Which transformations were performed on trapezoid PQRS to form trapezoid PꞌꞌQꞌꞌRꞌꞌSꞌꞌ? All dilations have a center of dilation at the origin and all rotations are around the origin.



A.
PQRS was reflected across the y-axis and then dilated by a scale factor of 4 to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

B.
PQRS was dilated by a scale factor of and then rotated 180° clockwise to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

C.
PQRS was dilated by a scale factor of and then translated 2 units right and 2 units down to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

D.
PQRS was dilated by a scale factor of 4 and then rotated 180° clockwise to form PꞌꞌQꞌꞌRꞌꞌSꞌꞌ.

Answer 14

and here is the image http://static.k12.com/calms_media/media/1574000_1574500/1574244/1/a589eeba804dea4927a0ce4815b39c4db01431c0/MS_IMC-141230-111002.jpg

Answer 15

well take the shortest side of both and you get your dilation

Answer 16

so 1/4

Answer 17

so its either b or c?

Answer 18

its not c =)

Answer 19

notice its rotated

Answer 20

so its b then?

Answer 21

yep =)

Answer 22

ah okay. i appreciate it. ive got two more to go then i can see the results >.> think you can help me out? :P

Answer 23

kk

Answer 24

i can =)

Answer 25

Triangle XYZ is similar to triangle XꞌꞌYꞌꞌZꞌꞌ.

Which two transformations were performed on triangle XYZ to produce triangle XꞌꞌYꞌꞌZꞌꞌ?

Choose exactly two answers that are correct.



A.
Triangle XYZ was dilated by a scale factor of to produce triangle XꞌYꞌZꞌ.

B.
Triangle XYZ was translated 3 units up to produce triangle XꞌYꞌZꞌ.

C.
Triangle XꞌYꞌZꞌ was translated 4 units down and 4 units left to produce triangle XꞌꞌYꞌꞌZꞌꞌ.

D.
Triangle XꞌYꞌZꞌ was dilated by a scale factor of 3 to produce triangle XꞌꞌYꞌꞌZꞌꞌ.

Answer 26

can u can choose multiple answers

Answer 27

let me grab the image.

Answer 28

its similar not congruent

Answer 30

you may not need it =)

Answer 31

what gets you a shape similar to another shape

Answer 32

the triangle pretty much looks enlarged.

Answer 33

what gets you a shape similar to the same shape

Answer 34

a dialation =)

Answer 35

oh its saying from large triangle to small one.

Answer 36

so it was made smaller.

Answer 37

so look at all the answers that have dilation =)

Answer 38

b and c are incorrect =)

Answer 39

d is one of the answers i feel.

Answer 40

oh wait never mind,

Answer 41

if its getting smaller its less than 1 if its getting enlarged its more than 1

Answer 42

i thought it was saying xyz quoted, but it was saying xyz non quoted >.>

Answer 43

so a dilation of 1/2 is going to make it small =)

Answer 44

answer is b =)

Answer 45

b it is then. hehe, next one! this is the final one for this quiz.

Answer 46

kk =)

Answer 47

Square ABCD has coordinates A (−10, 5), B (10, 5), C (10, 0), and D (−10, 0). Square AꞌBꞌCꞌDꞌ has coordinates Aꞌ (−10, −5), Bꞌ (10, −5), Cꞌ (10, 0), and Dꞌ (−10, 0). Square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ has coordinates Aꞌꞌ (−2, −1), Bꞌꞌ (2, −1), Cꞌꞌ (2, 0), and Dꞌꞌ (−2, 0).

Which transformations describe why squares ABCD and AꞌꞌBꞌꞌCꞌꞌDꞌꞌ are similar?

A.
Square ABCD was reflected across the x-axis and then dilated by a scale factor of to form square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ.

B.
Square ABCD was dilated by a scale factor of and then rotated 90° counterclockwise to form square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ.

C.
Square ABCD was reflected across the y-axis and then dilated by a scale factor of 5 to form square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ.

D.
Square ABCD was dilated by a scale factor of 5 and then rotated 90° counterclockwise to form square AꞌꞌBꞌꞌCꞌꞌDꞌꞌ.

Answer 48

wouldnt be c or d

Answer 49

scale factor would have to be 1/5

Answer 50

its a

Answer 51

alright. lets see how it turned out.

Answer 52

4/5, 80% i passed! thank you soo much! not sure what i wouldve done without you :3
