Given: ray bc bisects angle abd.

which pair of angles must be congruent?
a) ∠abd & ∠ebd
b) ∠abc & ∠dbe
c) ∠abc & ∠dbc
d) ∠abd & ∠cbdill mark brainliest if correct and give 50 pts.

C) ∠ABC & ∠DBC

Step-by-step explanation:

When a ray bisect an angle , then it divided the original angle into two congruent angles.

We are given that Ray BC bisects angle ABD.

Then, Ray BC divides ∠ABD into two congruent angles.

From the picture, The angle formed by it : ∠ABC & ∠DBC

So  ∠ABC & ∠DBC must be congruent.

Hence, the pair of angles must be congruent : ∠ABC & ∠DBC

answer: no
