6Improved Answer:-There are 360 degrees around a circle and any part of it is an arc.
The angle measure is: 90.01 degrees
False. There are infinitely many angles at the centre of the circle.
With a protractor. Or measure some distance, and use trigonometry.
It is an angle whose measure is 98/360 = 49/180 of a whole circle.
100
A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.
All of the ones in the figure.

False. There are infinitely many angles at the centre of the circle.
An angle whose measure is 76/360 of a full circle.
hi
180 degrees.
360 degrees
With a protractor. Or measure some distance, and use trigonometry.
The same as the central angle of the circle
