First of all, look at the figure, The ABC orientation is changed from clockwise to counterclockwise, so an odd number of reflections are involved.
Second, look at the answer choices. Right away, you notice that the last choice (E) involves two reflections. That cannot be the transformation you see. Since that is what the question is asking for, the appropriate choice for the transformation NOT done is ...
... E. reflection across the x-axis followed by a reflection across the y-axis
_____
I have to admit, I went through each of the choices to see if it would work to produce the image you see. All choices except E will do that. All that work turned out to be unnecessary.
Step-by-step explanation:
1. 3 and 2 are complementary because when you add them up, they give a toral of 90°.
2. As you may tell from the picture, and that they stated it in the question, angles 1 and 2 are added and they give a total of 90°.
3. If we consider that angle 3 is somewhat equal to angle 1, then the statement is true.
4. As I mentioned, if angle 1 and angle 3 are equal, then the statement is also true.
5. It was kind of proven above that angle 1 and angle two are similar, so this is true.
6. Like option 5, this is also the same thing.
I hope it helped!
The answer is D. You just move 10 units down from point F.
Is there a pic and a TRANSLATION is when you move a from one place to another with it remaining congruent. Hop that helps....
