Friend Hilmar Zonneveld is perfectly and absolutely right. Weight, being a vector, of an object will always act through the center of gravity. Also definition of centre of gravity confirms that whatever be the position the weight would always act through a point known to be center of gravity
Obtain a irregular 2-dimensional object that is easily handled. A piece of plywood would do nicely.Hang the object from various locations about the perimeter and draw a vertical line from the point of suspension to the opposite side of the object.Repeat this many times and you should note that all the lines intersect at the same point. This will be the center of gravity.Hang the object from the center of gravity, if you are using plywood a hook screw would do nicely. If you have the center of gravity then the object should hang horizontally.
Draw two lines from each corner. Where the two lines cross that is the centre of gravity PN This does not work for every object
That "point" in a body where the entire weight of the body can be represented to be present. Extend your knowledge by exploring where the center of gravity would be for metal shapes formed in the shapes of circular, square, rectanglar, hexagonal rings with metal rods. Where would the center of gravity be, on the ring or outside the ring?
Its possible, if you prepare ahead of time. In order to stand on one foot your center of gravity must line up with the leg you are standing on. When standing normally on two feet your center of gravity lines up with your crotch. If before lifting one leg you first bent your body sideways so the center moves over one leg, then you could lift the other leg and remain balanced.
Secret
It is at the intersection of the hexagon's lines of symmetry, i.e. the middle! It is the midpoint of any diameter.
It need not be - it depends on what the three lines are!

You can use plumb lines to find the center of gravity of an object.
Assume the room to be square or rectangle. The intersection of two lines from opposite corners is your center.
Bisect two of the angles. The intersection of the resulting lines is the triangle's centre.
You can use plumb lines to find its center of gravity. Hold it from one point and draw vertical line in direction of gravity (plumb line). Hold it from another point and do the same, and a third point if necessary; where the lines cross is center of gravity
No. The center of gravity of a wedding ring is in the space at the center of the ring. The center of gravity of the letter ' V ' is somewhere along the vertical line between the two slanted lines.
A closed planar figure with four right angles. This makes opposite sides parallel and of equal length and of course adjacent sides "normal" to each other ('normal' in geometry means at right angles). There is an inside and an outside. The center of gravity lies at the intersection of the diagonals and the intersection of the lines connecting opposite midpoints.
