To construct the line perpendicular to line m at point P, what should be done​ first?
1. Construct two points on m that are equidistant from P. Label the points A and B.
2. Construct two points on m so that one of the points is close to P and the other is far from P. Label the points A and B.
3. Construct two points on m that are on the left side of P. Label the points A and B.
4. Construct two points on m that are on the right side of P. Label the points A and B.
Construct two points on, m, that are on the right side of, P, . Label the points , A, and, B,
