If BD is the angle bisector of ∠ABC, then "∠ABC ≅ ∠ABD + ∠DBC" represents which of the following? Question 12 options: A) Angle addition postulate B) Symmetric property of congruence C) Transitive property of congruence D) Addition property of equality

∠ABC ≅ ∠ABD + ∠DBC

Step-by-step explanation:

The angle addition postulate is applied a larger angle is divided into two smaller angles that share the same vertices, the measure of the larger angle is the sum of the two smaller angles. That is the resulting angle formed by two angles which are side by side is the sum of the two angles. In triangle ABC, if ∠ABC is divided by line BD then ∠ABC is divided into ∠ABD and ∠DBC. Therefore:

∠ABC ≅ ∠ABD + ∠DBC

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
