For a triangle inscribed within a circle (and all points of the triangle touching the circle's circumference), if one side of the triangle is the diameter is it always assumed to be the hypotenuse?

thanks.

Yes. Because, a triangle with one side as a diameter forms a right-angle (90 degrees) opposite to the side that is a diameter. A side opposite to a right-angle is a hypotenuse. So, that side is a hypotenuse.

Another way of looking at it is

an angle BAC whose vertex A lies on a circle is said to be inscribed into the circle . The arc BC subtends an angle at the centre which will be twice BAC. But if BC is the diameter through the centre O , hypothetically angle BOC is 180°. So BAC is 90°.
