Question

if lines AC & BD Intersect each other at point 'O' Such that Angle AOB : Angle BOC as shown in the figure find Angle COD ​

Answer 1

Answer:

Angle COB = 90°

Step-by-step-explanation:-

°•° Angle AOB = angle BOC (given) ......|1|

Now, Angle AOB + angle BOC = 180°

=> Angle AOB + Angle BOC = 180°

=> Angle AOB + Angle AOB = 180° (From 1)

=> 2(Angle AOB) = 2 × 90°

=> Angle AOB = 90° ......|2|

Since, Angle AOB = Angle COD

Therefore, Angle COD = 90° (From 2)
