Below are sample questions representative of the exercises included on this worksheet and related GEO.15 Explain reasoning with clear mathematical language skill assessments:

Problem 1Difficulty: Mastery

Which explanation best justifies Step 3?

ADefinition of parallelogram.

BDefinition of rhombus.

CDefinition of trapezoid.

DDefinition of a kite: a quadrilateral with two distinct pairs of adjacent congruent sides.

Solution & Explanation:Having AB = AD and CB = CD matches the definition of a kite: two pairs of adjacent equal sides.

Problem 2Difficulty: Mastery

Which explanation best justifies that similarity statement?

ASegment addition postulate.

BASA Congruence.

CAA Similarity: two pairs of corresponding angles congruent imply similarity.

DCPCTC.

Solution & Explanation:Two corresponding angles determine the third angle, so the triangles have the same angle measures and are similar by AA.

Problem 3Difficulty: Mastery

Which explanation best justifies the factor of 4?

AAreas always scale by the same factor as lengths.

BArea scale factor is the square of the length scale factor: 2 squared equals 4.

CSimilar triangles always have equal areas.

DArea scale factor is the cube of the length scale factor.

Solution & Explanation:In similar figures, every length doubles, so two independent lengths (like base and height) each multiply by 2, making area multiply by 2 times 2 = 4.
