Sides are congruent Are rhombus diagonals perpendicular? You draw a figure and then verify the solution for clarity. asked by anne on February 2, 2008; math. A line that intersects another line segment and separates it into two equal parts is called a bisector. ⇒ ∠A + ∠B = 90° (Sum of adjacent angles of a parallelogram) If a quadrilateral is a parallelogram, then the diagonals bisect each other. The coordinates of vertex B a comma 0. The coordinate proof is a proof of a geometric theorem which uses "generalized " points on the Cartesian Plane to make an argument. She Theorem 8.7 If the diagonals of a quadrilateral bisect each other, then it is a parallelogram. Question: Write At Least One Formula Or Theorem That May Be Used In A Coordinate Proof. Accessibility Help. Τίτλος: Proof - Diagonals of a Parallelogram Bisect Each Other Περιγραφή: Proving that a quadrilateral is a parallelogram if and only if its diagonals bisect each other.
