WebLet ABC be a triangle, its incentre be I and its three excentres be I a, I b and I c. Then I a I b I c is the excentral triangle of ABC. A lies on the line I b I c and is the foot of the perpendicular from I a to that line, and similarly for B and C. Thus ABC is the pedal triangle (see later) of its excentral triangle. Further, these ... WebIn triangle geometry, the incentre of a triangle is the centre of the incircle, a circle which is within the triangle and tangent to its three sides. It is the common intersection of the three angle bisectors, which form a Cevian line system. The contact triangle has as vertices the three points of contact of the incircle with the three sides: it is the pedal triangle to the …
