Determine algebraic ally if the line whose equation is y= -5/6 x+9 is tangent at the point (6,4) to the circle whose equation is (x-4)2 +(y-2)=8 . Explain how you
know.

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.
