Q2 of 805 Page 14

Draw any line segment PQ. Take any point R not lying on it. Through R, draw a perpendicular to . (use a ruler and set square)

Step 1: Draw a line PQ. Point R lies above it.

Step 2: Place a ruler below the line parallel to it. Place the set square on top of the ruler such that its perpendicular edge is at the point R.

Draw a line along the edge, passing through R.

This gives us the required result.

Given some line segment AB, whose length you do not know, construct such that the length of is twice that of .

Draw any line segment AB. Mark any point M on it. Through M, draw a perpendicular to . (Use ruler and compasses)

Draw a line l and a point X on it. Through X, draw a line ssegment XY perpendicular to l.

Now draw a perpendicular to at Y. (use ruler and compasses)

Draw of length 7.3 cm and find its axis of symmetry.
