Also 120. Opposite angles are equal in a parallelogram.

Answer:

(A)

Step-by-step explanation:

Since from the given figure, GHIJ is a rhombus. A rhombus has all the properties as that of a parallelogram.

If ∠GHI=120°, then ∠GJI will also be equal to 120° because both ∠GHI and ∠GJI  are opposite to each other and also we know that the angles opposite to each other are always equal in a rhombus.

Thus, if ∠GHI=120°, then ∠GJI will also be equal to 120°

Hence, option (A) is correct.
