Let aeo be angle 1
Aed be angle 2
Deo be angle 3
Oec be angle 4

Angle 3=angle 4(V.O.A)
NOW WE WILL TAKE LINE CED
IN THIS
ANGLE 4+ANGLE +1 ANGLE 2 =180(As it is forming a straight line coz it is a tangent)
Angle 4=angle 1
Now angle (1+2+3)=180
Forming a straight line
Therefore o, e, o' are collinear
Hope it helps
