In the above bridge, line segment bd is the perpendicular bisector of line segment ac. for the bridge to be safe, triangle abd is congruent to triangle cbd. considering strictly the information that was given, what sequence of reasons can you use to prove that triangle abd is congruent to triangle cbd?

we can get the sequence of reasons with help of below explanation.

Step-by-step explanation:

Here It is given that, line segment BD is the perpendicular bisector of line segment AC. ( shown in below diagram)

By joining points B with A and B with C ( Construction)

We get two triangles ABD and CBD.

We have to prove that : Δ ABD ≅ Δ CBD

      Statement                                                  Reason

1. AD ≅ DC                                    1. By the property of segment bisector

2. ∠BDA ≅ ∠ BDC                        2. Right angles

3. BD ≅ BD                                   3. Reflexive

4.  Δ ABD ≅ Δ CBD                      4. By SAS postulate of congruence

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
