What else can I help you with?
What is a line that divides a figure into two parts that look exactly the same?
A line of symmetry
What does symmetry look like?
Symmetry is dividing a shape or figure in a certain way so that both sides are the same. Usually the line of symmetry, the line separating the shape, is a straight line.
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.
What figure always has the same numbers of lines of symmetry?
square and Equilateral Trangle
How do you know if a figure is symmetric about the line of symmetry?
A figure is symmetric about a line of symmetry if it can be folded along that line, and both halves match perfectly. This means that for every point on one side of the line, there is a corresponding point at the same distance on the opposite side. Additionally, you can check symmetry by reflecting points across the line; the reflected points should lie on the figure itself. If both conditions are satisfied, the figure is symmetric about the line.
What figure always has the same line of symmetry a square or a trapezoid?
A square.
What figure has rotational symmetry but not line symmetry?
A nonrectangular parallelogram has rotational symmetry, but not line symmetry. Additionally, shapes such as the letters S, N, and Z can be rotated to show rotational symmetry, although they do not have line symmetry.

What is line and point symmetry?
Oh, dude, line symmetry is when you can fold a shape in half and both sides match up perfectly, like a beautiful butterfly. Point symmetry is basically when a shape looks the same even after you give it a little spin, like a merry-go-round that never gets dizzy. So, like, line symmetry is all about folding, and point symmetry is more about twirling.

Do all figures have both line symmetry and rotation symmetry?
Not all figures have both line symmetry and rotational symmetry. Line symmetry, or reflective symmetry, occurs when a figure can be divided into two identical halves along a line, while rotational symmetry exists when a figure can be rotated around a central point and still appear the same at certain angles. Some figures may have one type of symmetry without the other, and others may have neither. For instance, a rectangle has both types of symmetry, while a scalene triangle has neither.
Is reflection and line symmetry the same thing?
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.
Is radial symmetry the same as line symmetry?
roughly
How do you use a mirror to test a figures line of symmetry?
Stand the mirror perpendicular to the figure. When it is positioned on the line of symmetry, the image in the mirror should be the same as the original image. However, this only works with your line of sight being the correct plane.
