Q. 4
Question
A __________ __________ is a positive angle whose vertex is at the center of a circle.
Step-by-Step Solution
Verified Answer
The solution is central angle .
1Step 1. Given information
A positive angle whose vertex is at the center of a circle
2Step 2. Calculation
A central angle is a positive angle whose vertex is at the center of a circle. The rays of a central angle subtend (intersect) an arc on the circle. If the radius of the circle is and the length of the arc subtended by the central angle is also , then the measure of the angle is one radian.
