6x² - 4x - 2
2(3x²) - 2(2x) - 2(1)
2(3x² - 2x - 1)
2(3x² - 3x + x - 1)
2(3x(x) - 3x(1) + 1(x) - 1(1))
2(3x(x - 1) + 1(x - 1))
2(3x + 1)(x - 1)

Which statement and reason accurately completes the proof? 3. ∠BDE ≅ ∠BAC; Corresponding Angles Postulate 5. ΔBDE ~ ΔBAC; Angle-

ElenaW [278]

Answer:

3. ∠BDE ≅ ∠BAC; Corresponding Angles Postulate 5. ΔBDE ~ ΔBAC; Angle-Angle (AA) Similarity Postulate

Step-by-step explanation:

3) Statement ∠BDE ≅ ∠BAC;

Corresponding Angles Postulate

The Corresponding Angles Postulate states that given two parallel lines, in this case DE and AC cut by a transversal one (AB) than these corresponding angles are congruent.

5) ΔBDE ~ ΔBAC; Angle-Angle (AA) Similarity Postulate

If two pairs of corresponding angles are congruent (∠D and ∠A, ∠E and ∠C) than these triangles are similar.
