When constructing a line perpendicular to a principal line that intersects at point P, what is the most important characteristic of the resulting angle at point P?
- The angle must be obtuse, greater than 90 degrees.
- The angle must be a straight line, 180 degrees.
- The angle must be acute, less than 90 degrees.
- The angle must be exactly 90 degrees. (correct)

In constructing a plane through point O that is perpendicular to a given oblique line, which of the following must be true?
- The plane must contain point O and intersect the oblique line at a 45-degree angle.
- All lines contained in the plane and passing through point O must be perpendicular to the oblique line. (correct)
- The plane must be parallel to the oblique line.
- The plane must intersect the oblique line at any random angle as long as it passes through point O.
