Ordinary Differential Equations
A curve which cuts every member of a given 1-parameter family of curves in the
same angle is called an isogonal trajectory of the family. If two 1-parameter
families have the property that every member of one family cuts every member of
the ...

CF and CF' are isogonal cevian lines for the angles A, B, C of a triangle ABC, and
if AD, BE, CF are concurrent, then AD', BE', CF' are also concurrent. (This
theorem was given by J. J. A. Mathieu in 1865, and was extended to three-space
by J.

Geometry for College Students
If X is in the interior of the triangle, then the three Cevians AX, BX, and CX are
interior, and thus their isogonal Cevians are interior. Hence they are necessarily
concurrent since they cannot be parallel. It follows that every point in the interior
of ...

Therefore the image of P under the similarity transforming the pedal triangle of P
into the triangle ABC will be P', which is exactly the isogonal conjugate. Now we
mention several elementary properties of the isogonal conjugation. 1. HP does ...

The isogonal of a Cevian line Q is the reflection of fi through the angle bisector of
LCAB. Similarly the isogonal of a Cevian line W is the reflection of 'fit through the
bisector of LABC and the isogonal of a Cevian line W is the reflection of W ...

Isogonal Lines and Points Two lines AS and AT through the vertex A of an angle
are said to be isogonal, or isogonal conjugates, if they are equally inclined to the
arms of LA, or equivalently to the bisector of LA (Figure 63). Figure 63 If a point ...
