Answer 1

Answer:

Step-by-step explanation:

i) AB IS PARALLEL TO FE GIVEN IN FIGURE

THEREFORE angle ABC = angle EFD (alternate angles are equal)

also from figure ..1

angle ACB = angle EDF  ..2

and AC=DE ..3

there fore triangle ABC is congruent to triangle EFD by AAS congruency criterion using 1, 2, 3

there fore by C.P.C.T- corresponding parts of congruent triangles

AB=FE proved

ii) again using CPCT

BC=DF

BC-CD=DF-CD ( equals subtracted by the same thing are equal )

BD=CF proved
