Intersection Point Calculator

An intersection point is the point where two or more lines or offsets meet. It is essential for plotting, layout, and alignment in surveying or civil engineering projects.

Enter the coordinates of the points defining the lines (X1,Y1,X2,Y2) and the calculator will compute the intersection point automatically. For advanced offsets, you can also use optional Point 3 coordinates.

This calculator supports Line-Line intersection and Offset-based intersection. Select the type from the dropdown to perform the correct calculation.

Yes, you can use negative coordinates to represent points in any quadrant on the Cartesian plane.

1. Enter coordinates for Point 1 and Point 2.
2. Optionally enter Point 3 if using offset.
3. Select Intersection Type.
4. Click “Calculate Intersection” to see the resulting intersection point.
