In the figure given below, OD=OC=OB. Find `angle DCB`.

In the given figure, find angle ADB , if angle DCB=100^@ and angle DBA =70^@ .

In the given figure, find angle ADB , if angle DCB=100^@ and angle DBA =70^@ .

In the given figure, OC.OD = OA.OB Show that : angle A = angle D " and " angle C = angle B.

In the Fig. given below, OB is the perpendicular bisector of the line segment DE, FA bot OB and FE intersects OB at the point C. Prove that 1/(OA) + 1/(OB) = 2/(OC)

In the given figure , BC = CE and angle 1 = angle 2. Prove that : Delta GCB = Delta DCB .

In the given figure, OA = OB and OD = OC. Show that (i) DeltaAOD cong DeltaBOC and (ii) AD||BC

In the given figures, OA = OB and OD = OC. Show that (i) triangleAOD = triangleBOC and (ii) AD||BC

In the given figure, Oa = OB and OC = OD. Which is the criteria to prove DeltaAOC ~=DeltaBOD .
