The meaning of PROJECTION is a systematic presentation of intersecting coordinate lines on a flat surface upon which features from a curved surface (as of the earth or the celestial sphere) may be mapped. How to use projection in a sentence. Did you know
The utility model can visually demonstrate various projections and projection transformations of points, lines, planes, crossing, parallel, intersect, vertical positions of the line and the line, intersect positions of the line and the plane, the plane and the plane, can explain projection of a ...

The projection of a line segment, which is joining two points on a line, is the line segment formed by projecting or pasting the endpoints of the existing line segment on the new line to form a 2-D figure.
Line PQ is x−3y+7=0 and the line through (1,0) perpendicular to it is 3x+y−3=0. Solving we get the foot of perpendicular as (1/5,12/5) which is the projection of (1,0) on the given line.
