# Nine-Point Circle tangent to inscribed circle and excircles

A

**nine-point circle**contains 3*midpoints*(*D, E, F*), 3*Euler points*(*N, O, P*), and 3*feet of altitudes*(*K, L, M*) of a triangle ([Triangle ABC]). The**nine-point circle**is also*tangent*to the*inscribed circle*and*excircles*of the triangle. Drag any of the vertices of the triangle to verify theses properties of the**nine-point circle**.## New Resources
