Draw a line l. Draw a perpendicular to l at any point on l. On this perpendicular choose a point X, 4 cm away from l. Through X, draw a line m parallel to l.

Line AB perpendicular to l is written as

Let l be a line and P be a point not on l. Through P, draw a line m parallel to l. Now join P to any point Q on l. Choose any other point R on m. Through R, draw a line parallel to PQ. Let this meet lat S. What shape do the two sets of parallel lines enclose?

Draw a line l ,also draw a line m parallel to l at a distance of 4 cm.

Draw any line segment bar PQ .Take any point R not on it.Through R draw a perpendicular to bar PQ .

Draw a line parallel to a line l at a distance of 3.5 cm from it .

Study the digram.The line l is perpendicular to line m. Is CE =EG?

Study the diagram. The line l is perpendicular to line m . Is CE = EG ?

Draw a lineAB.Mark a point C on it.Draw a line CD perpendicular to AB, using ruler and compasses.

Draw any line segment barAB .Mark any piont M on it.Through M draw a perpendicular to bar AB .(use ruler and compass).
