2.
Reflexive property

3.
Side-Angle-Side triangle congruence postulate

4.
Side-Side-Side triangle congruence postulate

5.
Corresponding parts of congruent triangles are congruent

6.
Given

Answer 1

The blanks in the proof is as follows

Blank 1 is given

Blank 2 is: HL congruence theorem

Blank 3 is: CPCTC

What is CPCTC?

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent

The CPCTC theorem says that if two triangles are proven to be congruent, then their corresponding parts (sides and angles) are also congruent.

With this theorem, we can say that AC is congruent to BD
