Points

1.) kayla wants to find the distance, ab, across a river. she walks along the edge of the river 75 ft and marks point c. then she walks 100 ft further and marks point d. she turns 90° and walks until her final location and marks point e. point e, point a, and point c are collinear.

2.) can kayla conclude that ∆abc and ∆edc are similar? why or why not?

3.) suppose de= 175 ft. what can kayla conclude about ab? explain. don’t forget to label your answer.
