**triangle**DeltaA^'B^'C^' is said to be inscribed in a**triangle**DeltaABC if A^' lies on BC, B^' lies on CA, and C^' lies on AB (Kimberling 1998, p. 184). Examples include the ...Given a point P and a

**triangle**DeltaABC, the Cevian**triangle**DeltaA^'B^'C^' is defined as the**triangle**composed of the endpoints of the cevians though the Cevian point P. A ...The

**triangle**bounded by the polars of the vertices of a**triangle**DeltaABC with respect to a conic is called its polar**triangle**. The following table summarizes polar triangles ...The extouch

**triangle**DeltaT_1T_2T_3 is the**triangle**formed by the points of tangency of a**triangle**DeltaA_1A_2A_3 with its excircles J_1, J_2, and J_3. The points T_1, T_2, ...The contact

**triangle**of a**triangle**DeltaABC, also called the intouch**triangle**, is the**triangle**DeltaC_AC_BC_C formed by the points of tangency of the incircle of DeltaABC ...Given a

**triangle**DeltaABC, the**triangle**DeltaH_AH_BH_C whose vertices are endpoints of the altitudes from each of the vertices of DeltaABC is called the orthic**triangle**, or ...Given a

**triangle**DeltaABC and a point P not a vertex of DeltaABC, define the A^'-vertex of the circumcevian**triangle**as the point other than A in which the line AP meets the ......
