No, in order to construct a polygon, you need at least three line segments.
A line can be vertical, diagonal, horizontal, and even curved. It can be any width, size, shape, position, direction, interval, or density. Points create lines and lines create shapes. A line can have other elements like color, texture, and movement applied to it.
You cannot have a shape without any line segments.
No shape does. However, a line and/or line segment is "one-sided".
Yes. Any equilateral shape can have both rotational and line symmetry.
A shape where when you take any two points in the shape the line connecting them will be totally in the shape.
To animate a line in After Effects, you can use the "Stroke" effect on a shape layer. Create a shape layer with a stroke, then keyframe the "End" property of the stroke to animate the line's appearance and movement.
The line of reflection is a line on which a shape is reflected to create its mirror image. It acts as a symmetry line, where each point on one side of the line is mirrored on the other side.
Any curved shape such as a circle, an ellipse, an oval, a wriggly line - as long as it does not have any corners.
If you change the slightest angle in any common shape, you create a new shape and since you can change the angles of any shape an infinite amount of times, you can essentially create infinite shapes. Meaning unfortunately, there is no direct answer for your question.
No. You can reflect any shape about a line but if the resulting image is not the same as the original, that line is not a line of symmetry.
A line of symmetry is when an imaginary line passes through the center of a shape vertically or horizontally creating a 'mirror image'
a line is a basic line drawn from a pencil a shape is a shape for example a star is a shape
