the circle
A zero-dimensional shape is a point.
Rotation. Though it does not have to be around a point in the shape: the centre of rotation can be outside the shape.
A(n) point is described as a location in space , and it has no size or shape.
Vertex
point of a shape or object
Any Closed shape have a meeting point
it's what you call circle
it is a form of a freezing shape
Point inflation is the point at which the curve changes its shape with the fixed rate of change. Point to point is the distance between the changes.
A circle has a round shape in which every point on the circle is the same distance from one point called "the center". The center of a circle is not on the circle.
The form of changing shape that involves rotation about a fixed point is called "rotation". In this transformation, every point on the object moves in circular paths around the fixed point, leading to a change in orientation while maintaining the same overall shape.
Let's call the point of reflection O. Take any point on the shape. Draw a line from that point to O and extend it beyond O for the same length (so that O is the midpoint of this line). The far end of the line is the image of the original point. Repeat for every point and you have the reflection of the original shape. In actual fact, if the shape is a polygon, then you only need to reflect the vertices and join up their images. Well defined curves will form the same shape and it should not be too difficult to reproduce their reflection. However, with a random wriggly curve you have no choice but to map each point.
