Answer:
Proved
Explanation:
Given that Alexa drew AB on a piece of a paper, and then folded the paper so that Point A was on Point B.
When Alexa folds the paper the line along the folding forms the line of reflection of A on B.
Now we have AB passing through the line of reflection such that AB cuts the folding line at mid point say C
AC=BC
And also C is right angled by the property of transformation of reflection on a line.
Hence Alexa is correct
