Arc Information Quadrantal Angles: 90^"◦" ,180^"◦" , _________, 360^"◦" angles

Answer explanation

The quadrantal angles are 0°, 90°, 180°, 270°, and 360°. The missing angle in the sequence is 0°, which is equivalent to 360° in a full rotation.

Central angle: is a angle whose vertex is at the ______________ of the circle.

Answer explanation

A central angle is defined as an angle whose vertex is at the center of the circle. Therefore, the correct answer is 'center'.
