n Figure, if EC || AB, ∠∠ECD = 70° and ∠∠BDO = 20°, then ∠∠OBD is

In the given figure, if ∠ABC = 20º, then∠AOC is equal to:(a) 20° (b) 40° (c) 12°(d) 10°

In the figure below, =m∠ABD92°, and m∠1 is 38° more than m∠2. Find m∠2

In Fig. 6.1, if AB || CD || EF, PQ || RS, ∠RQD= 25° and ∠CQP = 60°, then ∠QRS is equal

ABCD is a rhombus such that ∠ACB = 50°. Then find ∠ADB.

ABCD is cyclic quadrilateral Sides AB and DC, when produced, meet at E, and sides BC and AD, When produced, meet at F. If ∠BFA=60° and ∠AED=30°, then the measure of ∠ABC is:Choices:- 85° 65° 75° 90°
