TOPOGRAFÍA Para aproximar la longitud de un pan- tano, un topógrafo camina 250 metros del punto A al
punto B, después gira 75º y camina 220 metros al pun-
to C (vea la figura). Aproxime la longitud AC del pantano.

Def rotates 90 clockwise about point a to create d’ e’ f’. therefore, which equation must be true ?

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.
