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 figure always has the same numbers of lines of symmetry?
square and Equilateral Trangle
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 figures always have the same number of line symmetry?
all equilateral shapes do. that means that all sides are the same length.
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 figure that has rotational symmetry but not line symmetry is a figure that can be rotated by a certain angle and still look the same, but cannot be reflected across a line to create a mirror image of itself. An example of such a figure is a regular pentagon, which has rotational symmetry of 72 degrees but does not have any lines of symmetry. This means that if you rotate a regular pentagon by 72 degrees, it will look the same, but you cannot reflect it across any line to create a mirror image.

Is radial symmetry the same as line symmetry?
roughly
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.
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.
What figures always have the same number of line symmetry?
all equilateral shapes do. that means that all sides are the same length.
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.
Shapes with no line of symmetry?
All regular shapes have a line of symmetry. But you can get rid of its line of symmetry by making it irregular (so the angles aren't the same).
