As far as my knowledge is concerned a perfect circle can be drawn but drawing a perfect straight line is impossible as its definition itself is "locus of a point having infinite radius."
Geometrical compass To draw a perfect circle, and another compass for determining directions
It is the circle's diameter
because if it had 4 straight lines instead, we would call it a rectangle.
A circle....
Yes, it is indeed.
Radii
A circle is a round geometrical shape
A perfect circle can not be drawn by only using the hand. Even A computer won't be perfect as a circle is just lots of tiny straight lines put together. A perfect circle wold be that stays covered no mater how much u zoom in CHECk WITH MICROSOPE
A circle is a special type of geometrical figures. Each point on a circle corresponds to different angle.
No, some of the geometrical answers are wrong.
attach two to three pipe cleaners to make a perfect circle. attached another one and stand it straight up. them make another perfect circle of pipe cleaners and attached to the top end. The bottom circle will fit around the head then the straight pipe cleaner with another circle attached to the top forms the halo.
No one really because a circle is a natural geometrical shape seen throughout nature.
