Question Analysis

This question focuses on identifying the type of arc in a circle, testing the understanding of the differences between semi - circle arcs, major arcs, minor arcs, and radii.

Key Concept Explanation

Semi - circle Arc: An arc that measures exactly 180 degrees, or half of the circle's circumference.

Major Arc: An arc that is greater than a semi - circle (measures more than 180 degrees). It is named using three points (the two endpoints and a point on the arc).

Minor Arc: An arc that is less than a semi - circle (measures less than 180 degrees). It is named using its two endpoints.

Radius: A line segment from the center of the circle to a point on its circumference.
