AFEC is equal to the area ADEC, and therefore to half the area of the figure
ABEC. Proposition 29: To draw in a given circle two parallel chords cutting off,
between them, a given fraction m|n of the circle. (The fraction must be such that
we can ...

“if a come or a cylinder be cut by a plane not parallel to the base, the resulting
section is a section of an acuteangled cone, which is similar to a 6vpeds (shield)'.
Then, when a right cone had been cut by a plane cutting all the generators, and ...

Apollonius defines the azis of the cone as the straight line drawn from the vertex
of the cone through the centre of the circular base, and he first proves that all
sections of the cone parallel to that base are also circles, and that there is
another ...
