If you take any point on the edge (not coincident with point E), connect,,.

By,

It is known that the circumference of △ is the smallest.

In a rectangle,,, is the midpoint,

∴ ,,.

In 700 BC,

∴ Rt△∽Rt△, yes.

∴ .

∴ The coordinate of this point is (1, 0).

(2) As shown in the figure, make a symmetrical point about the axis, cut it at the side, connect it with the axis at the point, and cut it at the top.

A quadrilateral is a parallelogram.

The length of sum is a constant value,

∴ The points obtained at this time minimize the perimeter of the quadrilateral.

In 700 BC,

∴ Rt△∽Rt△, yes.

∴ .

∴ .

∴ The coordinate of the point is (0), and the coordinate of the point is (0).
