Suppose δdef  is the image of a translation of δabc. if  d  is at (−6, −2), what translation rule maps δabc  to δdef?



a.

t⟨9, 2⟩(δabc) = δdef

b.

t⟨9, –2⟩(δabc) = δdef

c.

t⟨−9, 2⟩(δabc) = δdef

d.

t⟨–9, –2⟩(δabc) = δdef

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?
