Question

ΔABC is reflected across the x-axis and then translated 4 units up to create ΔA′B′C′. What are the coordinates of the vertices of ΔA′B′C′ ?

A′(-3, 3), B′(-1, 1), C′(-2, 3)

A′(3, -3), B′(1, -1), C′(2, -3)

A′(3, -5), B′(1, -7), C′(3, -5)

A′(-3, 3), B′(-1, 1), C′(-2, -3)

Answer 1

Do you have a picture of the original triangle :p

Answer 2

Or the coordinates of it

Answer 3

yes

Answer 4

Can u post it :p

Answer 5

Answer 13

Its A.

Answer 14

thank you

Answer 15

what about this qurstion please

Answer 16

Quadrilateral ABCD underwent a sequence of transformations to give quadrilateral A′B′C′D′. Which transformations could not have taken place?

a reflection across the line y = x followed by a reflection across the line y = -x

a reflection across the x-axis followed by a reflection across the y-axis

a rotation 180° clockwise about the origin followed by a reflection across the line y = x

a reflection across the y-axis followed by a reflection across the x-axis

Answer 21

ummm. Those are traingles not quadrilaterals. Did you give the right image?

Answer 22

Triangles*

Answer 23

thats right you have to use triangle

Answer 24

But if you assume the question was worded incorrectly, and it meant to say triangle, I'm pretty sure its C

Answer 25

thank you what about this one

Answer 26

Which sequence of rigid transformations will not map the preimage ΔABC onto the image ΔA′B′C′ ?

a reflection across the y-axis followed by a reflection across the x-axis

a rotation 90° clockwise about the origin followed by a reflection across the x-axis

a rotation 180° clockwise about the origin followed by a reflection across the line y = -x

a reflection across the line y = x

Answer 28

Im pretty sure its C again. Like.. 80% Sure :p

Answer 29

it was wrong

Answer 30

Havent touched coordinate planes in a while :P

Answer 31

its ok\
