Question

1. construct a line that is perpendicular to \\(\overline{ab}\\) through point p. see example 4

Explanation:

Step1: Open the compass to a radius greater than half the length of \( \overline{AB} \).

With \( P \) as the center, draw arcs that intersect \( \overline{AB} \) at two points \( C \) and \( D \).

Step2: Open the compass to a radius greater than \( \frac{1}{2}CD \).

With \( C \) as the center, draw an arc above \( \overline{AB} \).

Step3: Using the same radius.

With \( D \) as the center, draw an arc that intersects the arc drawn in Step 2. Label the intersection point \( E \).

Step4: Draw the line \( \overline{PE} \).

The line \( \overline{PE} \) is perpendicular to \( \overline{AB} \) through point \( P \).

Answer:

The constructed line \( \overline{PE} \) is perpendicular to \( \overline{AB} \) through point \( P \).
