- AC is congruent to itself
- AC bisects angle BAD, so that angles BAC and DAC are congruent
- Both angles B and D are right angles, so they are congruent
This means triangles BAC and DAC are a pair of angle-angle-side triangles, so they are congruent to one another. Corresponding parts of congruent triangles are congruent, so the line segments BC and DC are congruent and have the same length.
Then

Answer:
The central angle of the arc is 288 degrees
Step-by-step explanation:
<u><em>The correct question is</em></u>
A circle has a circumference of 8. It has an arc of length 32/5 . What is the central angle of the arc,in the degrees?
we know that
The circumference of the circle subtend a central angle of 360 degrees
so
uing a proportion
Find out the central angle for an arc of length 32/5
