Key Concepts

Angle Bisector

When two lines intersect, the angle bisector is the line that divides the angle between them into two equal angles. Every point on an angle bisector is equidistant from the two sides of the angle. Therefore, if Elm Street and Grove Street intersect, placing Main Street along one of the angle bisectors would ensure that every point on Main Street is equidistant from the two streets.

Geometric Locus

A geometric locus is the set of all points that satisfy a particular condition. In this context, it refers to all the points that are equidistant from two given lines. Understanding the locus concept allows planners to determine the precise location where Main Street should be placed so that it maintains equal distance from Elm Street and Grove Street.

Equidistance

Equidistance means that the distance from a given point to two lines or objects is the same. For urban planning, ensuring equidistance guarantees that any point along Main Street will have the same proximity to both Elm Street and Grove Street, thus meeting the design requirement set by the planners.

Midline (or the Perpendicular Bisector in the case of parallel lines)

If Elm Street and Grove Street are parallel, the set of points equidistant from both is a line that runs parallel to them, exactly halfway between them. This line is analogous to a perpendicular bisector of any segment joining the two streets. Laying out Main Street along this midline would then guarantee the required equidistance.
