Below are sample questions representative of the exercises included on this worksheet and related GEO.30 Evaluate biconditional statements skill assessments:

Problem 1Difficulty: Mastery

During proof review, a student writes: "A polygon is regular if and only if all of its angles are congruent." Which option gives the correct truth value and the conditional-converse pair?

ATrue; if the polygon is regular, then all angles of the polygon are congruent; and if all angles of the polygon are congruent, then the polygon is regular.

BFalse; it lists only the conditional if the polygon is regular, then all angles of the polygon are congruent, not the converse.

CTrue; it lists only the converse if all angles of the polygon are congruent, then the polygon is regular, not the conditional.

DFalse; if the polygon is regular, then all angles of the polygon are congruent; and if all angles of the polygon are congruent, then the polygon is regular.

Solution & Explanation:The biconditional is false. The phrase if and only if represents both directions: if the polygon is regular, then all angles of the polygon are congruent; and if all angles of the polygon are congruent, then the polygon is regular. A regular polygon is equiangular, but a rectangle with unequal side lengths has all angles congruent and is not regular because its sides are not all congruent.

Problem 2Difficulty: Mastery

A classmate wants to use this biconditional as a precise geometry fact: "Quadrilateral ABCD is a parallelogram if and only if diagonals AC and BD have the same midpoint." Which choice correctly evaluates it and names the two directions? Use the planned diagram as a visual aid for the geometric relationship.

AFalse; if quadrilateral ABCD is a parallelogram, then diagonals AC and BD have the same midpoint; and if diagonals AC and BD have the same midpoint, then quadrilateral ABCD is a parallelogram.

BTrue; it lists only the conditional if quadrilateral ABCD is a parallelogram, then diagonals AC and BD have the same midpoint, not the converse.

CTrue; if quadrilateral ABCD is a parallelogram, then diagonals AC and BD have the same midpoint; and if diagonals AC and BD have the same midpoint, then quadrilateral ABCD is a parallelogram.

DFalse; it lists only the converse if diagonals AC and BD have the same midpoint, then quadrilateral ABCD is a parallelogram, not the conditional.

Solution & Explanation:The biconditional is true. The phrase if and only if represents both directions: if quadrilateral ABCD is a parallelogram, then diagonals AC and BD have the same midpoint; and if diagonals AC and BD have the same midpoint, then quadrilateral ABCD is a parallelogram. Diagonals of a parallelogram bisect each other, which means they share a midpoint; if the diagonals of a quadrilateral share a midpoint, they bisect each other and form a parallelogram.

Problem 3Difficulty: Mastery

Which evaluation is correct for the if-and-only-if statement "A point is in Quadrant II if and only if its x-coordinate is negative and its y-coordinate is positive." and for the two conditionals it represents?

AFalse; if the point is in Quadrant II, then the point's x-coordinate is negative and its y-coordinate is positive; and if the point's x-coordinate is negative and its y-coordinate is positive, then the point is in Quadrant II.

BTrue; if the point is in Quadrant II, then the point's x-coordinate is negative and its y-coordinate is positive; and if the point's x-coordinate is negative and its y-coordinate is positive, then the point is in Quadrant II.

CTrue; it lists only the conditional if the point is in Quadrant II, then the point's x-coordinate is negative and its y-coordinate is positive, not the converse.

DFalse; it lists only the converse if the point's x-coordinate is negative and its y-coordinate is positive, then the point is in Quadrant II, not the conditional.

Solution & Explanation:The biconditional is true. The phrase if and only if represents both directions: if the point is in Quadrant II, then the point's x-coordinate is negative and its y-coordinate is positive; and if the point's x-coordinate is negative and its y-coordinate is positive, then the point is in Quadrant II. Quadrant II contains exactly the points with x < 0 and y > 0.
