Reflect the figure over the line y = -4.

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?

Hi, can anyone show me how to do this problem? 100 points for this. in advance

What additional information could be used to prove abc =mqr using sas? check all that apply.
