Angles in Circles - PAP Geometry

Why must arcs AD and DE of circle C be congruent?

• They have adjacent central angles.

• Segments AE and BD bisect each other.

• Their central angles have the same measure.

• Segments AE adn BD are the same length.

• They look like they are congruent.

• 20^o and 35^o

• 30^o and 80^o

• 35^o and 65^o

• 45^o and 65^o
