Surveying The difference between a level line and a horizontal line is that both are same level line is normal to plumb line while horizontal line may not be normal to plumb line at the tangent point to level line level line is a curved line while hori-zontal line is a straight line horizontal line is normal to plumb line while level line may not be normal to the plumb line both are same level line is normal to plumb line while horizontal line may not be normal to plumb line at the tangent point to level line level line is a curved line while hori-zontal line is a straight line horizontal line is normal to plumb line while level line may not be normal to the plumb line ANSWER DOWNLOAD EXAMIANS APP
