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

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
