What reading level is The Modern Geometry of the Triangle book?
To quickly assess the difficulty of the text, read a short excerpt:
Let T-^T^Tg, be the Tangent Triangle, formed by drawing tangents to the ciroumoircle at A, B, G.
Then AT X , jBT 2 , GT t , are concurrent at K.
For, if q, r be the perpendiculars from T t on AO, AB, q _ TfisYnACTs _ ainB _ b r ~~ T X B sin ABT S ~ sin G ~ c ' Hence AT X passes through K ; so also do BT. 2 , CT S .
Note that T x is the point of intersection of the tangents at B and G, whose equations are y/c + a/a = 0, a/a + b/B = 0, so that the n.c. of 2\ are (—a, b, c).
122. The Lemoine Point... A of 1^1,- In the figure of the preceding section, it will be seen that the Lemoine Point K of the inscribed triangle ABG, is the Gergonne Point (32) of T^T,.
Therefore the point M, which is the Gergonne Point of ABG, is the Lemoine Point of XYZ.
But XYZ and 7^1, are homothetic, the centre of similitude being
