Incentre of pedal triangle
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 ... WebThe incentre is also the point of intersection of internal bisectors of the triangle. The radius of the in circle is called the in radius of triangle and is denoted by ‘r’.
