Question

Which statement and reason accurately completes the proof?
Select one:
a. 4. ΔBDE ∼ ΔBAC; Side-Angle-Side (SAS) Similarity Postulate
5. ∠B ≅ ∠B; Reflexive Property of Equality

b. 4. ∠B ≅ ∠B; Reflexive Property of Equality
5. ΔBDE ∼ ΔBAC; Angle-Angle (AA) Similarity Postulate

c. 4. ΔBDE ∼ ΔBAC; Side-Angle-Side (SAS) Similarity Postulate
5. ∠A ≅ ∠C; Isosceles Triangle Theorem

d. 4. ∠A ≅ ∠C; Isosceles Triangle Theorem
5. ΔBDE ∼ ΔBAC; Angle-Angle (AA) Similarity Postulate

Answer 1

SAS Similarity

Side-angle-side similarity. When two triangles have corresponding angles that are congruent and corresponding sides with identical ratios as shown below, the triangles are similar.

AA Similarity

Angle-angle similarity. When two triangles have corresponding angles that are congruent as shown below, the triangles are similar.
Based on these it should be easier to eliminate and choose your best option.

Answer 2

what do u think

Answer 3

I have no idea which one it'd be bc I suck at Geometry. ):
