Properties of Line segment

The projections of line segment on the coordinate planes are 6,2 and 3 .Then find the length of line segment is

Write the properties of congruent segments.

The midpoint of a line segment is (-4,-2) .If (-6,4) is one end, then the other end of line segment is

If the projections of a line segment on the axes are 3, -4, 12 then the length of the segment and d.c.'s of the line are

The projections of a line segment on x,y,z axes are 12, 4, 3. The length and the direction-cosines of the line segment are :

If the porjections of a line segment on the axes are 2, 1, 2 then the length of the segment and d.c.'s of the line are

The projections of a line segment on the coordinate axes are 12,4,3 respectively. The length and direction cosines of the line segment are
