Question

two unequal angles of a parallelogram are in the ratio 2:3 Find Al it's angles​

Answer 1

Step-by-step explanation:

Let ABCD be a parallelogram  



Then, AD ∥ BC and AB is a transversal.  

Therefore, A + B = 180° [Since, sum of the interior angles on the same side of the transversal is 180°]  

Similarly, ∠B + ∠C = 180°, ∠C + ∠D = 180° and ∠D + ∠A = 180°.  

Thus, the sum of any two adjacent angles of a parallelogram is 180°.  

Hence, any two adjacent angles of a parallelogram are supplementary.
