Question

Dum hai to ye sawaal hal kar ke dikhaye ​

Answer 1

Answer:

Step-by-step explanation:

If OE IS INTERSECTING angleAOC. So angleAOE=angleCOE. Similarly angleBOF=angle COF. angleAOE+angleCOE+ angleBOF+angleCOF=180. angleAOE+angleAOE+. angleBOF+angleBOF=180. 2angleAOE+2angleBOF=180. 2(angleAOE+angleBOF)=180. angleAOE+angleBOF=90. This shows that AOB is a straight line.
