The following words, sentences that are correct.Inscriptions on a table in a circle.Let ABCD be a circle.It is necessary to inscribe a circle in the square ABCD.Draw two diameter AC and BD ABCD's circle at right angles to one another, and participate in BC, AB, CD, da.Then, since it equals zero, and EA E for ED as usual, and at right angles, so the base is equal to AB, ad base.For the same reason, each line segment BC and CD, also equal to each of the straight line AB and Ad, so a rectangle ABCD is an equilateral triangle.I say that it is also a right angle.Because, from a straight line BD is the diameter of a circle ABCD, so bad is the half circle so bad angle is right.For the same reason, ABC, each CCD and CDA is also so right rectangle ABCD is a right angle.But it is also equilateral triangle proves it is a table, and will be inscribed in a circle.The ABCD has been inscribed in a given circle.
