True.

angle1 = angle 2=20 degrees

Step 1

Let

angle COA ( it goes from 40 to 80 degrees)(from A to C), then

angle COA= 80 degrees - 40 degrees

angle COA= 40 degrees

Step 2

ray OB divides 2 COA into two angles

angle 1 =BOA 0 it goes from 40 to 60

angle |= BOA=20 degrees

ray OB divides 2 COA into two angles

angle 2 =COB 0 it goes from 60 to 80

angle 2= COB=20 degrees

then

angle1 = angle 2=20 degrees

therefore

ray OB divides 2 COA into two angles of equal measure
