Below are sample questions representative of the exercises included on this worksheet and related GEO.24 Critique arguments and detect flawed reasoning skill assessments:

Problem 1Difficulty: Mastery

After proving triangle ABC congruent to triangle DEF, a student writes: By CPCTC, side AB is parallel to side DE. Which correction is valid?

ACPCTC can prove any relationship between corresponding parts, including parallelism.

BThe triangles must be similar, not congruent, before CPCTC can be used.

CParallelism follows automatically from any two congruent sides.

DCPCTC gives congruent corresponding parts, not parallel lines; use angle relationships or slopes to prove parallelism.

Solution & Explanation:CPCTC allows conclusions like AB = DE or angle A = angle D after triangle congruence. Parallelism requires a separate reason such as congruent corresponding angles or equal slopes.

Problem 2Difficulty: Mastery

A theorem says: If a quadrilateral is a square, then its diagonals are congruent. A student concludes: If a quadrilateral is not a square, then its diagonals are not congruent. Which critique is best?

AThe conclusion is the valid contrapositive of the theorem.

BThe original theorem is false because square diagonals are not congruent.

CThe student used the inverse, which is not logically equivalent; a nonsquare rectangle has congruent diagonals.

DThe conclusion is true because only squares can have congruent diagonals.

Solution & Explanation:For 'if p then q,' the inverse 'if not p then not q' is not guaranteed. Rectangles that are not squares show the conclusion can fail.

Problem 3Difficulty: Mastery

Two triangles have corresponding side lengths 6 and 12, 7 and 14, and 9 and 18. A student says the triangles cannot be proved similar because no angles are given. Which correction is valid?

AThe student is correct because at least one angle is always required for similarity.

BThe three corresponding side ratios are equal, so the triangles are similar by SSS similarity.

CThe triangles are congruent by SSS because all ratios equal 2.

DThe triangles are not similar because the larger side lengths are different from the smaller ones.

Solution & Explanation:All three pairs of corresponding sides have the same ratio, 1/2 from smaller to larger. SSS similarity proves the triangles are similar without angle measures.
