Fill in the blanks with one of the following: AAS, ASA, HL, SAS or SSS.

1. If segment AB `cong` segment CB and segment BD bisects <ABC, then `Delta` ABD`cong` `Delta` CBD by ______.

2. If <ADB `cong` <CDB and <A`cong` <C, then `Delta` ABD `cong` `Delta` CBD by_____.

3. Segment BD is an altitude and segment AB`cong` segment CB, then `Delta` ABD`cong` `Delta` CBD by_____. Then <A`cong` <C because Corresponding parts of `cong` `Delta` s are `cong`

1. If segment AB is congruent to segment CB and segment BD bisects angle ABC, then triangle ABD is congruent to triangle CBD by **SAS.**

2. If angle ADB is congruent to angle CDB and angle A is congruent to angle C, then triangle ABD is congruent to triangle CBD by **AAS**.

3. Segment BD is an altitude and segment AB is congruent to segment CB, then triangle ABD is congruent to triangle CBD by **HL**. Then angle A is congruent to angle C because corresponding parts of congruent triangles are congruent.
