A right angle measures 180^(@)

Find angleA+angleB+angleC+angleD

An angle measuring 180^(@) is called

In a quadrilateral ABCD, angleA + angleC = 180^(@) , then angleB + angleD is equal to

In the given figure, angle DBC = 65^@ , angle BAC = 35^@ and AB = BC then the measure of angle ECD is equal to: दिए गए चित्र में, angle DBC= 65^@ , angle BAC = 35^@ और AB=BC तो angle ECD का माप ज्ञात करे

In a Delta ABC angle A + angle B = 145^(@), 2 angle B + angle C = 180^(@) Find angle A and angle B

In the adjacent figure, a line 'l' intersects two other lines P, Q and angle1+ angle2 gt 180^@ then show that ´angle3 + angle4 gt 180^@ .

In a DeltaABC , angleA+ angle B=125^(@) and angle B+ angle C=150^@ . Find all the angle of Delta ABC.
