Question 2
Using GeoGebra, illustrate Pascal's Theorem by plotting:
- an arbitrary conic X, (this should be defined using an equation ax2+bxy+cy2+dx+ey+f=0, with sliders for each of the coefficients)
- six points A, B, C, A', B', and C' on X,
- cross-lines defined by AB', AC', BA', BC', CA', and CB'.
- the "Pappus Line" connecting the intersections of the cross-lines AB' and BA', . Be sure that you can move around the points A, B, C, A', B', C' as well as the sliders defining the conic.
