A Case of Three Rotating Lines and the Point “O.” (Continued.)

Published online by Cambridge University Press:  03 November 2016

Extract

15. Let X1, Y1, Z1 be the second points in which AH, BH, CH meet the circle GH

Then GX1 HX, and hence ║ BC,

X1X =⅓AX;

tan PX1X= 3 tan PAX = 3 tan θ,

i.e. -PX1 X= ø.

But OX1H = OGH= ø; 0X1P is a straight line.
