... a be a given straight line and a point . A which is not lying on this straight line Let us draw a straight line c through it to. some point of a straight line perpendicular to it The line ... ... of a straight line perpendicular to it The line c intersects the line a at point C. Now we draw the line parallel to line b, so . that line b passes through point A Then line ... (Planometry)
