Construct a triangle with sides 5 cm, 6 cm and 7 cm and then construct its incircle. State how the centre and the radius are found.
Original Khojo Papers practice question — not from a past board paper.
Answer
The centre is where the bisectors of the angles meet, and the radius is the perpendicular distance from that point to any side.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The incentre is equidistant from all three sides, and the locus of points equidistant from two sides is the bisector of the angle between them.
