Reflect AABC in BC. What kind of figure will result? How would your answer change if ABC is isosceles? a right triangle with right angle at A? a right isosceles trianglewith right angle at A?

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.
