Explain how to use the midpoint formula to prove or disprove that ABCD is a parallelogram. A) Prove that AC and BD do not have the same midpoint. The diagonals of a parallelogram cannot have the same midpoint. B) Prove that AD and BC have the same midpoint. All sides of a parallelogram are congruent; therefore, they have the same midpoint. C) Prove that AC and BD have the same midpoint. The diagonals of a parallelogram bisect each other; therefore, they have the same midpoint. D) Prove that AB and CD do not have the same midpoint. All sides of a parallelogram are congruent; therefore, they have different midpoints.

Question 9(Multiple Choice Worth 6 points)(05.01 LC)The figure below shows triangle NRM with r2 = m2 + n2:Triangle NRM has legs m and n, and r is the length of its longest side.Ben constructed a right triangle EFD with legs m and n, as shown below:Triangle EFD has legs m and n and hypotenuse f.He made the following table to prove that triangle NRM is a right triangle:Statement Reason1. r2 = m2 + n2 Given2. f2 = m2 + n2 Pythagorean Theorem3. f2 = r2 Substitution4. f = r Square Root Property of Equality5. Triangle NRM is congruent to triangle EFD SSS Postulate6. Angle NRM is a right angle ?7. Triangle NRM is a right triangle Angle NRM is a right angleWhich reason best fits statement 6? Triangle Proportionality Theorem All sides of both the triangles are equal Corresponding parts of congruent triangles are congruent Triangle EFD has two angles which measure less than 90°
