Question
Draw a linear pair of angles. Bisect each of the two angles. Verify that the two bisecting rays are perpendicular to each other.

Answer


Steps of construction:
  1. Draw two angles DCA and DCB forming linear pair.
  2. With center C and any radius draw an arc which intersects AC at P and CD at Q and CB at R.
  3. With center P and Q and any radius draw two arcs which intersect each other at S.
  4. Join SC.
  5. With Q and R as center and any radius draw two arcs which intersect each other at T.
  6. Join TC.
Therefore $\angle\text{SCT}=90^\circ$
