if you look at the picture which axis is inbetween the two images?
the x axis
so the answer is D? ..but why how come its not a translation but rather a reflection? can you explain please?
if you look in a mirror what do you see?
a relection...but it also looks like a translation...
so in other words...how can I tell the difference?
a translation is when you take something and move it elsewhere so efectivly a reflection is also a translation.
the answer is B. B. vertical translation of 10 units. It cannot be a reflection, note that H has a vertex at (4,2) and the reflection about X-axis will have vertex at (4,-2) but the figure H prime (the bottom one) has a vertex at (4,-3). Thus on reflection the figures won't overlap. Only way to do that is to slide down the figure above 10 units to the bottom.
it cannot be a reflectio cuz, in mirror if u see, preimage is at same distance from the image. but here thats not the case..
ahhh, many pardons i did not look at the picture in detail.
it does look like a reflection cuz it has horizontal symmetry.. if it was translated just 9 units down, then its both translation and reflection
okay. well thanks :)
