Hey, I need help on two questions and also could you check the other two.

3. (03.06 MC) In AABC shown below, DE is parallel to AC D E The following two-column proof with missing statements and reasons proves that if a line parallel to one side of a triangle also intersects the other two sides, the line divides the sides proportionally: Statement Reason 1. DE | | AC 1. Given 2. AB is a transversal that intersects two parallel lines. 2. Conclusion from Statement 1. 3. 3 4. ZB ~ LB 4. Reflexive Property of Equality 5. 5. 6 BD BE 6. Converse of the Side-Side-Side Similarity Theorem BA BC Which statement and reason accurately completes the proof? (2 points) 3. ZBDE = ZBAC; Corresponding Angles Postulate 5. ABDE ~ ABAC; Angle-Angle (AA) Similarity Postulate 3. ABDE ~ ABAC; Corresponding Angles Postulate 5. ZBDE ~ ZBAC; Angle-Angle (AA) Similarity Postulate 3. ZBDE ~ ZBAC; Congruent Angles Postulate 5. ABDE ~ ABAC; Angle-Angle (AA) Similarity Postulate 3. ZBDE = ZBAC; Congruent Angles Postulate 5. ABDE ~ ABAC; Side-Angle-Side (SAS) Similarity Postulate\fGiven: AABC is a right triangle. Prove: a2 + b2 = c2 C C B y D The following two-column proof with missing justifications proves the Pythagorean Theorem using similar triangles: Statement Justification Draw an altitude from point C to AB Let BC = a CA = b AB = C CD = h DB = y AD = X y+ x =c cac_b a y'b x a2 = cy; b2 = cx a2 + b2 = cy + b2 a2 + b2 = cy + cx a2 + b2 = c(y + x) a2 + b2 = c(c) a2 + b2 = c2 Which is not a justification for the proof? (2 points) Pieces of Right Triangles Similarity Theorem Side-Side-Side Similarity Theorem Substitution Addition Property of EqualityUse MBC below to answer the question that follows: which fact is not used to prove that ABC is similar to BEE? (2 points) The sum of angles A and B are supplementary to angle C. O Segments AC and DE are parallel. 0 AB is a transversal line passing AC and DE. 0 Angle B is congruent to itself clue to the reexive property
