  1. ABCD is a rhombus with ∠ ABC = 56°, then ∠ ACD is equal to :


    1. 90°
    2. 60°
    3. 56°
    4. 62°
    5. None of these
Correct Option: D

From above given figure , we can see that
ABCD is a rhombus .
Since AB = BC

∴ ∠BAC = ∠BCA = 1(180° - 56°) = 62°
2

Also as AB || CD and AC transversal .
So ∠BAC = 62° = ∠ACD (By Alternate interior angles property)
∴ ∠ACD = 62°.
