Answer:
A.[tex]m\angle ABD=m\angle ABC[/tex]
Step-by-step explanation:
We are given that a ray BA bisects angle DBC.
We have to find true statement .
Angle bisector property:When a ray bisect any angle then the angles made by bisection of angle are equal.
When ray BA bisects angle DBC
Then, [tex]m\angle ABD=m\angle ABC[/tex]
By angle bisector property.
Therefore, option A is true.
Answer:A.[tex]m\angle ABD=m\angle ABC[/tex]
