Nikita began with the figure shown.
Two straight lines A B, B C intersecting at B in an angle.
She completed the following actions to construct the angle bisector of ∠ABC, but made a mistake in one of the steps. Select the step in which her mistake was made.
Step 1: She placed the compass on point B and drew an arc which intersects ray BA at point D and ray BC at point E.
Step 2: Next, she placed the compass on point D and drew an arc on the interior of ∠ABC.
Step 3: Then, she placed the compass on point C and drew an arc on the interior of ∠ABC, which intersects the previous arc.
Step 4: She labeled the intersection of the two arcs as point F and drew the ray BF, which represents the angle bisector of ∠ABC.
Her mistake was made in Step 3: Then, she placed the compass on point C and drew an arc on the interior of ∠ABC, which intersects the previous arc.
The correct step would be to place the compass on point E, which is the intersection of the arc drawn in Step 1, and draw an arc that intersects the previous arc from Step 2.
