Answer:
Option A : copy the angle
Explanation:
We can see that to make congruent triangles he first copied the segments
He copied the segment and drew segment FG
Then he copied the length of BH and then keeping compass on point F cut the line segment FG at I
Then he measured the angle ABC and then intersect the previous arc at J
So, we can see that he just copied the angle
So, his recent completed step was copy the angle .
So, Option A is correct
Hence Option A copy the angle is true .
