How is the point-to-line distance calculated?

It uses the perpendicular distance formula: d = |A*x0 + B*y0 + C| / √(A² + B²), where Ax + By + C = 0 is the line equation and (x0, y0) is the point.

What coordinate formats are supported?

The calculator handles positive, negative, and fractional coordinate points, automatically centering the SVG graph to fit the bounding box of the points.

Cartesian Coordinate System principles

Coordinate geometry connects algebra and geometry. By mapping points onto a Cartesian plane, geometric curves are expressed as algebraic equations, allowing automated pathing, structural modeling, and spatial clearance analysis.
