Study Notes
Ptolemy's Theorem
- Ptolemy's theorem is a mathematical concept that relates to the geometry of a cyclic quadrilateral.
- Verbal expression of Ptolemy's theorem: "The sum of the products of the opposite sides of a cyclic quadrilateral is equal to the product of the diagonals."
- The converse of Ptolemy's theorem states that if the sum of the products of the opposite sides of a quadrilateral is equal to the product of the diagonals, then the quadrilateral is cyclic.
Corollary Regarding Equilateral Triangle
- Ptolemy's theorem yields a corollary regarding an equilateral triangle inscribed in a circle, stating that the product of the sides of the equilateral triangle is equal to three times the square of the radius of the circle.
- The corollary states that if an equilateral triangle is inscribed in a circle, then the product of the sides of the triangle is equal to three times the square of the radius of the circle.
