Two Geometry Puzzles

October 11, 2020 pm31 11:59 pm

I haven’t asked a math question in a long, long time. Not sure if anyone who does them is still reading…

Can a Polygon Be Constructed?

Under what circumstances is it possible, given n ≥ 3 segments, to form a polygon?

Or, if you prefer, under what circumstances, given n ≥ 3 segments, is it not possible to form a polygon?

The segments may be connected in any order.

Can a Quadrilateral, but not a Trapezoid, be Formed?

Are there four segments from which it is possible to construct a quadrilateral, but from which it is not possible to construct a trapezoid?

The segments may be connected in any order.

    Trapezoid is new to me, I’ll have to think about it when I’m more awake!
