A. Point [tex]\( L \)[/tex] is the midpoint of [tex]\(\overline{J K}\)[/tex]

B. Line [tex]\( s \)[/tex] intersects [tex]\(\overline{J K}\)[/tex] at a [tex]\(180^{\circ}\)[/tex] angle

C. Line [tex]\( s \)[/tex] is parallel to [tex]\(\overline{J K}\)[/tex]

D. Line [tex]\( s \)[/tex] is perpendicular to [tex]\(\overline{J K}\)[/tex]

E. [tex]\( J L = K L \)[/tex]



Answer :

Certainly, let's analyze each statement one by one to determine which must be true given that line [tex]\( s \)[/tex] is the perpendicular bisector of line segment [tex]\( \overline{JK} \)[/tex] and intersects [tex]\( \overline{JK} \)[/tex] at point [tex]\( L \)[/tex].

Statement A: Point [tex]\( L \)[/tex] is the midpoint of [tex]\( \overline{JK} \)[/tex]

Since line [tex]\( s \)[/tex] is the perpendicular bisector of [tex]\( \overline{JK} \)[/tex], it divides [tex]\( \overline{JK} \)[/tex] into two equal parts. This means point [tex]\( L \)[/tex] must be the midpoint of segment [tex]\( \overline{JK} \)[/tex].
Thus, Statement A is True.

Statement B: Line [tex]\( s \)[/tex] intersects [tex]\( \overline{JK} \)[/tex] at a [tex]\(180^\circ\)[/tex] angle

A perpendicular bisector intersects the segment it bisects at a right angle ([tex]\(90^\circ\)[/tex]), not a straight line angle ([tex]\(180^\circ\)[/tex]).
Thus, Statement B is False.

Statement C: Line [tex]\( s \)[/tex] is parallel to [tex]\( \overline{JK} \)[/tex]

A perpendicular bisector cannot be parallel to the segment it bisects because it intersects the segment at a right angle.
Thus, Statement C is False.

Statement D: Line [tex]\( s \)[/tex] is perpendicular to [tex]\( \overline{JK} \)[/tex]

By definition, a perpendicular bisector intersects the segment it bisects at a right angle ([tex]\(90^\circ\)[/tex]).
Thus, Statement D is True.

Statement E: [tex]\( JL = KL \)[/tex]

Since point [tex]\( L \)[/tex] is the midpoint of [tex]\( \overline{JK} \)[/tex], the lengths of [tex]\( \overline{JL} \)[/tex] and [tex]\( \overline{KL} \)[/tex] are equal.
Thus, Statement E is True.

Summarizing, the true statements are:
- A. Point [tex]\( L \)[/tex] is the midpoint of [tex]\( \overline{JK} \)[/tex].
- D. Line [tex]\( s \)[/tex] is perpendicular to [tex]\( \overline{JK} \)[/tex].
- E. [tex]\( JL = KL \)[/tex].

The final applicable answers are:
True, False, False, True, True.
