true or false 1. If the length of the parabolic curve is 10 meters, Point PI is 5 meters away from Point PC, horizontally. 2. If the stationing of PC of the parabolic curve is 1+200, the curve length or Lc is 50 meters, and the length of the curve or L is 47 meters, the stationing of PT is 1+250. 3. If the vehicle enters a vertical curve with slope or grade at -3%, the curve is a sag curve.
