Below are sample questions representative of the exercises included on this worksheet and related GEO.22 Use precise definitions and valid justifications skill assessments:

Problem 1Difficulty: Mastery

Proof snippet: 1) Given: In △ABC, AB = AC. 2) Statement: ∠B ≅ ∠C. Which theorem justifies Step 2?

AAA Similarity

BIsosceles Triangle Base Angles Theorem

CConverse of the Isosceles Triangle Theorem

DThird Angles Theorem

Solution & Explanation:In an isosceles triangle, the base angles opposite the congruent sides are congruent.

Problem 2Difficulty: Mastery

Proof snippet: 1) Given: In △ABC, ∠B ≅ ∠C. 2) Statement: AB = AC. Which theorem justifies Step 2?

ASSS Congruence Theorem

BIsosceles Triangle Base Angles Theorem

CTriangle Sum Theorem

DConverse of the Isosceles Triangle Theorem

Solution & Explanation:If two angles in a triangle are congruent, then the sides opposite them are congruent; opposite ∠B is AC and opposite ∠C is AB, so AB = AC.

Problem 3Difficulty: Mastery

Proof snippet: 1) Given: ∠1 ≅ ∠2. 2) Given: ∠2 and ∠3 form a linear pair. 3) Statement: m∠1 + m∠3 = 180°. Which justification best supports Step 3?

AVertical Angles Theorem

BTriangle Sum Theorem

CCorresponding Angles Postulate

DSubstitution into the linear-pair supplementary relationship

Solution & Explanation:Since ∠2 and ∠3 form a linear pair, m∠2 + m∠3 = 180°. With ∠1 ≅ ∠2, substitute m∠1 for m∠2 to get m∠1 + m∠3 = 180°.
