Answer:
perpendicular bisector: OP
drew it in the picture
Explanation:
perpendicular lines are lines that intersect at a right (90 degrees) angle.
so I drew the line segment AB with CD intersecting at point X at 4 cm from point A, OP intersecting at point Z at 5 cm, and LM intersecting at point Y at 7 cm.
perpendicular bisector is a line or a segment perpendicular to a segment that passes through the midpoint of the segment.
the midpoint of line AB is at 5 cm because the total length is 10 cm (it’s just the middle)
OP is the perpendicular bisector because it’s at the midpoint 5 cm
