Product Description
Geometry PROOFS: Congruence, Similarity, Coordinate proofs (Geometry Curriculum in 5 min tasks - Unit 15)
Writing Proofs to show Congruence, Similarity and other properties of figures; Connecting Proofs to other units of Geometry / Daily Geometry Regents Prep with Quick Check tasks .
Track students’ progress consistently, efficiently and frequently with Daily Geometry Checkpoints / HS Geometry curriculum.
Solutions are included for these THREE Units on Proofs: Congruence, Similarity, Coordinate Proofs.
This collection of tasks is composed of performance indicators embedded in HS Geometry state assessments and is a good source of pre-tests, test-prep, quizzes, exit slips, bell-ringers.
It can be used as a workbook, homework practice, flipped classroom supplement.
It contains:
-45 assessment tasks (A and B versions) + Keys w/solutions.
-58 pages
15.1_Basic proof of triangle ≅-ce (midpoint, sas).
15.2_Basic proof of triangle ≅-ce (⏊, sas).
15.3_Δ ≅-ce by SAS (vertical angles).
15.4_Δ ≅-ce by SAS /ASA (transversal and ⃦ lines; vertical angles; CPCTC).
15.5_Δ ≅-ce by SSS (coordinate proof).
15.6_Δ ≅-ce by SSS/SAS (example of Δ-s in a ʘ: Theorem “Central angles are ≅” is needed; CPCTC; ≅ implies =).
15.7_Δ ≅-ce by AAS/ASA (example of Δ-s in a ʘ; transversal and ⃦ lines; vertical angles; CPCTC).
15.8_Δ ∼-ty by AA/SAS (example of Δ-s in a ʘ: Theorem “Inscribed angles, intercepting the same arc are ≅” is needed; AA).
15.9_Δ ∼-ty by AA/SAS (example of Δ-s in a ʘ: transversal and ⃦ lines; vertical angles; AA).
*15.10_Prove that the original and its image after D-2 (D2) are similar (Theorem of similarity by corresponding sides in proportion is stated SSS∼SSS; coordinate prove)

18.1_Prove that the figure is a right Δ.
18.2_Prove that the figure is an isosceles Δ.
18.3_Prove that the figure is a parallelogram, but is neither a rectangle, nor a rhombus.
18.4_Prove that a parallelogram is a rectangle, but not a square.
18.5_Identify/Prove the exact type of a quadrilateral (right trapezoid).
18.6_Determine whether the figure is a parallelogram, using lengths of sides (review distance between two points).
18.7_Determine whether the parallelogram is a rectangle, using lengths of diagonals (review distance between two points).
18.8_Determine whether the parallelogram is a rectangle, using midpoints of its diagonals (review midpoints of segments).
18.9_Determine whether the parallelogram is a rectangle, using properties of its angles (review slopes of ⊥ lines).
18.10_Determine whether the figure is a parallelogram, using slopes (review slopes of ∥ lines).
18.11_Determine whether the figure is a parallelogram, using slopes and lengths on one pair of opposite sides ONLY (review slopes of ∥ lines, distance between two points).
18.12_Prove the original and its image after a reflection in a line are congruent (SSS).
*18.13_Prove that the original and its image after a given transformation, are similar. Simplifying radicals.
