Based on the construction marks and the fact that the semicircles intersect the horizontal line segment at points K and L, we can deduce that the segments KO and OL are equal in length.
Therefore, we can conclude that:
\( KO = OL \)
So the correct response would be:
KO¯¯¯¯¯¯¯¯ = OL¯¯¯¯¯¯¯
This assertion is based on the geometric properties of the figure and symmetry, as the line segment connecting the points where the semicircles intersect is vertical and reflects the equivalence of the segments KO and OL.
