3v/ 2 ~ 4.2
The point that is equal distance from the endpoints of a line segment is the midpoint.
In three dimensions, the solid defined as being bound by the set of points at a given distance form a point is a sphere. In two dimensions, the figure defined as being bound by the set of points at a given distance from a point is a circle. In one dimension, a line segment is bound by the two points at a given distance from a point.
Surveying terminology. The measure of distance along a slope. The distance of a line where elevation changes from point 1 to point 2

It the point is on the line the distance is 0. If the point is not on the line, then it is possible to draw a unique line from the point to the line which is perpendicular to the line. The distance from the point to the line is the distance along this perpendicular to the line.
circle
Yes.
The 'perimeter' of any closed figure drawn on paper means the total distance around it. If the figure consists of straight lines, then the perimeter is the sum of the lengths of all the straight-line pieces. If you set an ant down at a certain point on the figure and he started walking along the line, the perimeter is the distance he would have to walk in order to wind up at the point where he started.
The distance is 0.
The point that is equal distance from the endpoints of a line segment is the midpoint.
the length of a perpendicular segment from the point to the line
The letters S and N have point symmetry but not line symmetry.
The length of a line segment that starts at the point and is perpendicular to the original line.
