What similarity statement can you write relating the three triangles in the diagram? a. ghf ~ gih ~ hif b. hif ~ gih ~gfh c. gfh ~ghi ~hif d. ghf ~igh ~hif

Ok so from the updated link,
IFH, IGH, and GHF are right triangles
since IFH is a triangle, IF is a straight line (180 degrees)
angle IGH is 90 so therefor angle FGH is also a right angle aka IGH=FGH

GHI+GHF=90

all angles in a triangle =180
therefor, IGH+GHI+GIH=180
FGH+GHF+HFG=180
IGH+GHI+GIH=FGH+GHF+HFG
since IGH=FGH subtract that from both sides
GHI+GIH=GHF+HFG
also, since IGH=FGH=90, 180-90=90 so
GHI+GIH=GHF+HFG=90
we also know that
GHI+GHF=90
therefor
GIH=GHF and GHI=HFG

sorry if this is confusing extremelly confusing

so
we know that if 3 angles ina triangle are congruent, trignles are similar
so we know that
GHF=GIH and
HIF=GIH and
GHI=GFH

the answer is A

 

Answers: the graph is translated down 1 unit and the domain and range of g(x) is the same as the domain and range of f(x).
