Answer 1

Answer:

a+b+c=b

Step-by-step explanation:A

D =

C

In the adjoining figure, the sides BA and DC of a quadrilateral ABCD have been produced

to E and F respectively.

Prove that: a + b = x + y.

(Hint: 6° + ZA = 180°, aº +. ZC = 180°.

..a° +6° + ZA + ZC = 360°.

But, xº + yº + ZA + ZC = 360°. [Angles of a quadrilateral]
