Draw a right angle and construct its bisector.

The below given steps will be followed to construct a right angle and its bisector.

(1) Draw a line *l* and mark a point P on it. Draw an arc of
convenient radius, while taking point P as centre. Let it intersect
line *l* at R.

(2) Taking R as centre and with the same radius as before, draw an arc intersecting the previously drawn arc at S.

(3) Taking S as centre and with the same radius as before, draw an arc intersecting the arc at T (see figure).

(4) Taking S and T as centres, draw arcs of same radius to intersect each other at U.

(5) Join PU. PU is the required ray making 90º with line *l*.
Let it intersect the major arc at point V.

(6) Now, taking R and V as centres, draw arcs with radius more than RV to intersect each other at W. Join PW.

PW is the required bisector of this right angle.
