What else can I help you with?
Could an odd number of reflections ever be a rotation?
Of course. A reflection of any symmetric shape about a line perpendicular to its axis of symmetry will be a rotation of 180 degrees around the point on its axis of symmetry which is halfway between the pre-image and the image.
What are the four kinds of symmetry?
Rotation: move the object around the plane. Each rotation has a center and an angle.Translation: move the object on the plane without rotating or reflecting it. Each translation has a direction and distance.Reflection: mirror image of the object. Always has a mirror line.Glide Reflection: combination of a reflection and translation along the mirror line.
What is the relation between order of rotation and number of axes of symmetry of a geometrical figure?
The order of rotation of a geometrical figure refers to the number of times it can be rotated to look the same within a full 360-degree rotation. The number of axes of symmetry is the number of lines that can be drawn through the figure such that each side is a mirror image of the other. Generally, figures with higher orders of rotation tend to have more axes of symmetry, as rotational symmetry often implies reflective symmetry. However, this is not a strict rule, as some shapes may possess high rotational symmetry yet fewer axes of symmetry.
Is rotation always creates a congruent image to the original figure?
Figures are congruent if and only if they are related by a translation, reflection, or rotation, or some combination of these transformations.
What are the three transformations of math?
The 3 transformations of math are: translation, reflection and rotation. These are the well known ones. There is a fourth, dilation, in which the pre image is the same shape as the image, but the same size in the world

What are transformations that result is an image that is the same shape and size as the original?
They are translation, reflection and rotation. An enlargement changes the size of the image.
The new figure formed by a transformation?
The new images can be: A translation, a reflexion, an enlargement and a rotation.
Is rotation always creates a congruent image to the original figure?
Figures are congruent if and only if they are related by a translation, reflection, or rotation, or some combination of these transformations.
What is the property of a figure that can be reflected across a line so that the image coincides with the pre image?
The property is Reflection Symmetry, Line Symmetry or Mirror Symmetry
What is reflectional summetry?
Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection

When a line of symmetry divides an image its spells the image into two congruent parts on either side of the line symmetry?
true
When a line of symmetry divides an image, it splits the image into two congruent parts on either side of the line of symmetry?
true
What is a mirror-like image?
Symmetry
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.
