Is line symmetry the same as diagonal symmetry?
No, line symmetry and diagonal symmetry are not the same. Line symmetry, also known as reflection symmetry, occurs when a figure can be divided into two equal halves that are mirror images of each other across a line. Diagonal symmetry, on the other hand, occurs when a figure can be divided into two equal halves that are mirror images of each other across a diagonal line. In essence, while both involve symmetry across a line, the orientation and positioning of that line differ between the two types of symmetry.
Can a figure with two or more lines of symmetry can have rotational symmetry?
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
Are lines of symmetry also diagonals in polygons?
Lines of symmetry in polygons are not necessarily diagonals. A line of symmetry divides a shape into two identical halves, while a diagonal connects non-adjacent vertices of a polygon. In some cases, a diagonal can serve as a line of symmetry, but this is not true for all polygons. Therefore, while there can be overlap, the two concepts are distinct and not synonymous.
Are all plane figures closed?
No, take a semicircle, it is a plane figure and is open. Or a parabola is also open and a plane figure.

What are line symmetric figures?
Line symmetric figures, also known as reflections or mirror images, are shapes that can be divided into two identical halves by a straight line, called the line of symmetry. When the figure is folded along this line, both halves match perfectly. Common examples include shapes like squares, rectangles, and certain triangles. The line of symmetry can be vertical, horizontal, or diagonal, depending on the figure.
If a line of symmetry divides a figure into two congruent isosceles trianges must the figure be a square?
No. it can also be a rectangle
What is the definition of reflectional symmetry?
An image has Reflectional Symmetry if there is at least one line which splits the image in half so that one side is the mirror image of the other. Reflectional symmetry is also called line symmetry or mirror symmetry because there is a line in the figure where a mirror could be placed, and the figure would look the same.
