Question

in the given figure, ABCD and EFGC are
parallelograms, if ZD = 120°, then the
measure of ZF is
(i) 160
(ii) 120°
(iii) 60°
(iv) 40°​

Answer 1

Answer:

(iii)60 degrees

Step-by-step explanation:

As angle ADE and angle CEF  are corresponding angles they are equal that is angle CEF is also 120 degrees, as CEF and EFG are co-interior angles they should be supplementary that is they both should add up to 180 degrees.

120 + EFG = 180

EFG = 180 - 120

EFG = 60
