Answer

Answer:

C. The sum of their measures is 180°.

Explanation:

Step1: Recall circle - arc property

Two intersecting diameters divide a circle into four arcs. Adjacent arcs together form a semi - circle.

Step2: Determine arc measure

The measure of a semi - circle is 180°. So, the sum of the measures of two adjacent arcs created by two intersecting diameters is 180°.
