Question

Quadrilaterals ABCD and EFGH are shown in the coordinate plane.

Determine congruence by selecting the ONE correct sequence of isometric transformations that maps ABCD onto EFGH.


A.
a translation of 3 units to the right, followed by a reflection across the x-axis.

B.
a translation of 12 units downward, followed by a reflection across the y-axis

C.
a reflection across the y-axis, followed by a reflection across the x-axis

D.
a reflection across the line with equation y = x

Answer 1

You can start this by looking at just one point

Take point A - you can see that it corresponds wiht point E

so take each of the transformations and apply it to point A
(e.g a translation of 12 units downward, followed by a reflection across the y-axis
will move point A first to y=-8 and then to x=+4 )

IF that translation moves Point A to co-incide with point E then this is probably the correct answer. You need to check one ogther point in the same way to make sure)

Answer 2

so c?

Answer 3

have you checked that it works for a number of points?

If so then go with it.

Answer 4

i'm pretty sure :/ idk

Answer 5

just do what I said

take point A, using answer C

where will it be after reflection in y axis
where will THAT point be after refletion in X axis
is the result that A transforms to E?

do the same for one of the other points....
