Property
An inscribed angle is said to intersect an arc on the circle. The arc is the portion of the circle that is in the interior of the angle. The measure of the intercepted arc (equal to its central angle) is exactly twice the measure of the inscribed angle.
This single property has a number of consequences within the circle. For example, it allows one to prove that when two chords intersect in a circle, the products of the lengths of their pieces are equal. It also allows one to prove that the opposite angles of a cyclic quadrilateral are supplementary.

Famous quotes containing the word property:
“Never let the estate decrease in your hands. It is only by such resolutions as that that English noblemen and English gentlemen can preserve their country. I cannot bear to see property changing hands.”
—Anthony Trollope (1815–1882)
“Strange and predatory and truly dangerous, car thieves and muggers—they seem to jeopardize all our cherished concepts, even our self-esteem, our property rights, our powers of love, our laws and pleasures. The only relationship we seem to have with them is scorn or bewilderment, but they belong somewhere on the dark prairies of a country that is in the throes of self-discovery.”
—John Cheever (1912–1982)
“It is a well-settled principle of the international code that where one nation owes another a liquidated debt which it refuses or neglects to pay the aggrieved party may seize on the property belonging to the other, its citizens or subjects, sufficient to pay the debt without giving just cause of war.”
—Andrew Jackson (1767–1845)
