The measure of the arc created by a central angle is 57°. What type of arc is this?
minor arc
major arc
semi-circle
To determine the type of arc created by a central angle, we need to consider the measure of the angle itself.
A minor arc is an arc whose measure is less than 180°. A major arc is an arc whose measure is greater than 180°. A semi-circle is a special case where the arc measure is exactly 180°.
Based on the given information that the measure of the arc created by the central angle is 57°, we can conclude that this is a minor arc.
To determine the type of arc created by a central angle, we need to examine the measure of the angle.
In this case, the central angle measures 57°.
If the measure of the central angle is less than 180° (but greater than 0°), then the arc is a minor arc. Therefore, if the arc measures 57°, it is classified as a minor arc.
Hence, the type of arc created by a central angle of 57° is a minor arc.
Well, I know it's not a semi-circle since that would be 180 degrees.
