Dual Properties
Kites and isosceles trapezoids are dual: the polar figure of a kite is an isosceles trapezoid, and vice versa. The side-angle duality of kites and isosceles trapezoids are compared in the table below.
| Isosceles trapezoid | Kite |
|---|---|
| Two pairs of equal adjacent angles | Two pairs of equal adjacent sides |
| One pair of equal opposite sides | One pair of equal opposite angles |
| An axis of symmetry through one pair of opposite sides | An axis of symmetry through one pair of opposite angles |
| Circumscribed circle | Inscribed circle |

Famous quotes containing the words dual and/or properties:
“Thee for my recitative,
Thee in the driving storm even as now, the snow, the winter-day
declining,
Thee in thy panoply, thy measur’d dual throbbing and thy beat
convulsive,
Thy black cylindric body, golden brass and silvery steel,”
—Walt Whitman (1819–1892)
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
