As shown in the graph, δghi ≅ δg'h'i', since this is a vertical shift, and δg'h'i' ≅ δg''h''i'', since this is a horizontal shift. we can also show that triangles ghi and g''h''i'' are congruent directly, by using the translation a.(x, y) → (x + 3, y - 4). b(x, y) → (x - 3, y + 1). c.(x, y) → (x + 2, y + 2). d.(x, y) → (x + 4, y - 5).

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

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?
