**The angle between two altitudes of a parallelogram through the vertex of an obtuse angle of the … is 60°. Find the angles of the…**

###### Answers:

Let the parallelogram be ABCD, in which ∠ADC and ∠ABC are obtuse angles. Now, DE and DF are two altitudes of parallelogram and angle between them is 60°.

**using the basic properties if you solve you will get 60,60,120,120 degrees**
