when to angles are congruent, you can see red circular lines around the angles. When the number or lines around the angle is the same, that means the angle is congruent (if that made any sense XD)
18. Angle CBJ has 2 circular lines around the angle. The only other angle that has that is angle FHG. therefore, FHG and CBJ are congruent
19. Similarly, FJH has 3 lines and so does angle BJA, so therefore, FJH and BJA are congruent.
20. Since angle EFD has one red line around the angle, and so does JAB, they are both congruent. Therefore, that means the value of the angle is the same for both. So, since EFD = 75 defgrees, JAB = 75 degrees as well
ANSWERS:
18. angle FHG
19. angle BJA
20. 75 degrees
Hope this helped ^-^
