Look at the figure below:

triangle abc has measure of angle abc equal to 90 degrees. e is a point on the hypotenuse ac such that the segment be is perpendicular to ac. d is a point outside the triangle on the right of e so that triangle edc has the measure of angle edc equal to 90 degrees.

which triangle is similar to triangle aeb?

triangle cde

triangle bac

triangle bec

triangle ced

Reflect the point (7,0) across the y-axis

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?
