Answer: Yes to all of them (I THINK?)
a. Yes
b. Yes
c. Yes
Explanation:
I think what this is asking is if after doing each transformation, will the angle measures stay the same. Like will they still be 45, 45, 90,...the simple answer is yes because we aren't changing the size of the triangle or anything. It's only being reflected, rotated or moved over to another spot and that doesn't change angle degrees. The coordinates would change but not the actual angles. There are no physical changes to the angles itself like shrinkage, so I'm guessing they will stay the same.
At least I hope that's what it means.
