Draw a triangle ABC. Draw its angle bisectors. The angle bisectors pass through a point.
Recall the procedure to draw angle bisectors:
- With B as centre and with a convenient radius draw an arc of a circle to cut AB and AC at X and Y.
- With X and Y as centres and radius equal to more than half of XY draw arcs of circles to intersect at S. Join BS.
- BS is the angle bisector of B.
- The angle bisectors pass through a common point (I). This point is called "Incentre".
