In each circle below, a 50° angle with a vertex at the center of the circle is drawn. How are minor arc lengths CD and EF related?

Circle A and B are shown. Line segments D A and C A are radii with lengths of 8 centimeters. Angle D A C is 50 degrees. Line segments F B and E B are radii with lengths of 2 centimeters. Angle F B E is 50 degrees.

They are the same because the central angle measure is the same.

The arc lengths are proportional: Arc C D = 2 arc E F.

The arc lengths are proportional: Arc C D = 4 arc E F.

The arc lengths are proportional: Arc C D = 6 arc E F.
