How do you divide circle into 21 parts?
One possible way: draw 21 radii, each forming an angle of 17.142857.. degrees with another radius. Another option: the question does not require the 21 parts to be equal. So make twenty cuts where each cut divides a segment into two (equal or unequal) parts.
Can a reflex angle be 360 degrees?
No. A reflex angle is strictly greater than (not equal to) 180 degrees and strictly less than (not equal to) 360 degrees.
Relationship between degree of measure of a central angle and the arc it intercepts?
Arc length is equal to radius times the angle the arc subtends (makes) at the centre of the circle, but the angle needs to be in radians. Set your calculator to radians instead of degrees, or, to change degrees to radians, divide by 180 and times pi. The formula comes from the fact that the length of the arc is proportional to the circumference of the circle in the same ratio as the angle at the centre is to the complete revolution at the centre, so length of arc: circumference of circle = angle size : 360o arc/(2*pi*r) = angle in degrees/360 or angle in radians/(2*pi) so arc length is angle in degrees divided by 360, times the circumference of the circle. Answer will be in the same measurement unit as the radius.
Divide an angle into equal angles?
A bisector is a line that divides an angle into two equal parts. For example: in a right-angle (90 degrees) a bisector will cut the angle into two, each being 45 degrees.
Do a bisector of an angle divides the angle into right angles?
A bisector divides an angle into two equal parts. Therefore, if the bisector begins on the middle of a straight line (180 degrees) then the bisector must form a right-angle with the straight line.
If a line is a bisector of an angle then it divides the angle into two equal angles If a line divides an angle into two equal angles then it is a bisector of the angle?

What is a quarter circle in degrees of an angle?
A quarter circle corresponds to an angle of 90 degrees. This is because a full circle is 360 degrees, and dividing it into four equal parts results in each part measuring 90 degrees. Therefore, a quarter circle represents one-fourth of a complete rotation.
A circle is divided into 10 partsWhat is the angle measure of four of those parts?
A circle is 360 degrees. If they are equal parts, they are 36 degrees apiece, or 144 degrees.
What is the measure of the angle by the straight sides of the circle divided into 5 equal parts?
A circle has no straight sides but if you mean a circle that has been divided into 5 equal sectors then the angle of each sector is 72 degrees subtended by each arc of the circle.
If a circle was divided into 6 equal parts what would be the degree measure of the central angle?
It is 60 degrees
A circle is divided into 18 equal parts how many degrees is the angle for 5 parts?
A circle has a total of 360 degrees. If it is divided into 18 equal parts, each part measures ( \frac{360}{18} = 20 ) degrees. Therefore, the angle for 5 parts is ( 5 \times 20 = 100 ) degrees.
A bisector is a ray that divides an angle into two angles of equal is called an angle bisector?
Not exactly.A ray that divides an angle into two angles of equal measure is called an angle bisector.
What fraction of a circle is equal to an angle of 90?
One quarter of a circle is equal to 90 degrees. 360 / 4 = 90 or 1/4 x 360 = 90
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.
What is a ray that divides an angle into two equal parts?
An angle bisector.
