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