From a point O, four lines OA, OB, OC and OD should be drawn respectively such that /_AOB=/_COD and /_BOC=...

A (1, -2) and B (2, 5) are two points. The line OA, OB are produced to C and D respectively such that OC=2OA and OD=20B . Find CD

In the given figure, rays OA, OB, OC and OD are such that /_AOB = 50^(@) , /_ BOC = 90^(@) , /_ COD = 70^(@) , and /_ AOD = x^(@) . Then, the value of x is

In figure OA*OB=OC*OD. Show that /_A=/_C and /_B=/_D

In the given figure, from the point P two tangents PA and PB are drawn to a circle with centre O and radius 5cm. From the point O, OC and OD are drawn parallel to PA and PB respectively. If the length of the chord AB is 5cm, then what is the value of (in degrees) of angleCOD ?

O is any point inside a triangle ABC. The bisector of /_AOB,/_BOC and /_COA meet the sides AB,BC and CA in point D, and F respectively.Show that ADxBExCF =DBxECFA

In the given figure, AOB is a straight line and OC is a ray such that /_AOC = (3x+20)^(@) and /_BOC = (2x - 10)^(@) . Find the value of x and hence find (i) /_AOC (ii) /_BOC

In the given figure,rays OA, OB, OC and OD are such that angleAOB=56^(@) , angleBOC=100^(@) , angleCOD=x^(@) and angleDOA=74^(@) ,Find the value of x .

In Figure,rays OA,OB,OC, OD and OE have the common end point O .Show that /_AOB+/_BOC+/_COD+/_DOE+/_EOA=360^(@)
