## X(275) (CEVAPOINT OF ORTHOCENTER AND SYMMEDIAN POINT)

 Interactive Applet

You can move the points A, B and C (click on the point and drag it).
Press the keys “+” and “−” to zoom in or zoom out the visualization window and use the arrow keys to translate it.

You can also construct all centers related with this one (as described in ETC) using the “Run Macro Tool”. To do this, click on the icon , select the center name from the list and, then, click on the vertices A, B and C successively.

This applet was built with the free and multiplatform dynamic geometry software C.a.R..

Trilinears           csc 2A sec(B - C) : csc 2B sec(C - A) : csc 2C sec(A - B)
Barycentrics    sec A sec(B - C) : sec B sec(C - A) : sec C sec(A - B)

X(275) lies on these lines:
2,95    4,54    13,472    14,473    17,471    18,470    25,262    51,107    53,288    76,276    83,297    94,324    98,427

X(275) = isogonal conjugate of X(216)
X(275) = isotomic conjugate of X(343)
X(275) = X(276)-Ceva conjugate of X(95)
X(275) = cevapoint of X(4) and X(6)
X(275) = X(I)-cross conjugate of X(J) for these (I,J): (6,54), (54,95)
X(275) = crosssum of X(217) and X(418)
