If 8 euros we're worth $9 and 24 euros were worth $27 write an equation of the form y equals kx to show the relationship between the number of euros and the value in dollars where y is dollars and x is euros

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
