If ABCD is a cyclic quadrilateral with ∠A = 50 degrees, ∠B = 80 degrees then ∠C and ∠D are _____
Question
Geometry:
If ABCD is a cyclic quadrilateral with ∠A = 50 degrees, ∠B = 80 degrees then ∠C and ∠D are _____
In a cycling Quadrilateral, the opposite angles are supplementary i.e. they add up to 180 degrees.
Means A + C=180 and B + D= 180.
As given, ∠A = 50; A + C = 180
=> 50 + C = 180
=> C = 130.
