Answer:
A' (11, 4), B' (-10, -6), C' (7, -9)
Step-by-step explanation:
Since you are reflecting over the y-axis, you take the opposite of the x value. So if the x is positive, make it negative. If the x is negative, make it positive. The y coordinate stays the same.
-12 would be it because 2 negatives make a positive so -11+23 is -12
The correct answer is SAS.
It's given that BC is congruent to CD and AC is congruent to CE. And by Vertical Angles theorem, Angle BCA is congruent to DCE.
