Question

the diagram below shows a nearly completed construction of a line through a that is perpendicular to \overleftrightarrow{ab}. complete the construction.

Explanation:

Step1: Identify intersection points

Points D and E are intersections of two circles.

Step2: Draw line through D and E

Construct a straight line connecting D and E; this line passes through A and is perpendicular to $\overrightarrow{AB}$.

Answer:

Draw the line segment connecting points D and E. This line is the perpendicular to $\overrightarrow{AB}$ through A.
