What is the dimension of a plane angle?

The graduation of an angle would usually be expressed in degrees, of which there are 360 for a complete circle.


How do you calculate a right angle?

A right angle is always 90 degrees. That is 1/4 of a complete circle, which would be 360 degrees.


What is the relationship between a circle and an angle?

An angle is the measurement of two lines drawn from the centre of a circle. A circle is 380 degrees. So in an angle of 90 degrees, one line would be vertical at 0 degrees, and the second line would be horizontal at 90 degrees. So the relationship is that you can't have one without the other.


What angle is bigger than reflex?

A full circle would be the only answer. As a circle is 360 degrees.


How many degressin a right angle?

A right angle is always formed by two perpendicular lines. These lines would split a circle into quarters. There are 360 degrees in a circle, so one quarter would be 90 degrees. A right angle is always 90 degrees.


If an angle that has a measure of 51.4 degrees is inscribed in a circle what is the measure of its intercepted?

102.8 degrees I think but it depends. If the angle is a central angle it is 51.4 degrees but other than that I think it would be 102.8 degrees.


Can a parallelogram always be inscribed in a circle?

No. For example, if one angle measures 100 degrees, and its adjacent angle is 80 degrees, then the opposite angles would be either 200 or 160 degrees, but in order for a quadrilateral to be inscribed in a circle the opposite angles would have to equal 180 degrees. A parallelogram can be inscribed in a circle if it is a rectangle.


How much is 9 degrees?

Degrees are used to measure the arc of a circle. A full circle is 360 degrees, and a half circle 180. so 9 degrees would be 1/40th of a complete circle.


Which quadrant of the circle would contain the angle 45 degrees?

Any angle (in standard position) between zero and 90 degrees is in the first quadrant.


What is a 180' circle?

There is no 180' circle that would be half a circle. A complete circle is 360 degrees A circle is 360º no matter what its size is.


What fraction of a 360 degree circle is 30 degrees?

To find the fraction of a 360 degree circle that is 30 degrees, you would divide the angle measurement by the total angle of the circle. So, 30 degrees divided by 360 degrees equals 1/12. Therefore, 30 degrees is 1/12 of a 360 degree circle.


How do you draw a 450 degree angle?

For a 450 degree angle, you would subtract 360 from 450, which gives you 90 degrees. Therefore, you will draw a 90 degree angle. Explanation below: There are only 360 degrees in a circle. A 450 degree angle would go around a circle once completely, then it would stop at the 90 degree angle mark.
