I was looking at a ASUS Prime Z490-P LGA 1200, and the specs say it has a graphics co-processor: GTX 1060. What does this mean? [closed]

I was looking at a ASUS Prime Z490-P LGA 1200, and the specs say it has a graphics co-processor: GTX 1060. What does this mean? Does this mean that I do not need to install a separate graphics card, and that the graphics will process through the motherboard? Thank you!

euclidean geometry – 3 chords inclined at $pi/3$ of a convex closed curve that intersect at their midpoint always exist

In “The penguin dictionary of curious and interesting geometry” David Wells mentions the following property of closed convex curves without a reference nor a proof.

“Given any closed convex curve, it is possible to find a point P, and three chords inclined at $pi/3$, such that P is the mid-point of all three”.

Can anyone redirect me to some literature or provide an argument for such a property?
