What type of transformation are the pre-image and the image congruent figures?
isometry
What happens if the scale factor is greater than 1?
The image is bigger than the pre-image.
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 the shape of an object before a transformation called?
pre image is the answer if is any help now to anyone
What is definition of pre-image in math?
The definition of pre-image in math:For a point y in the range of a function ƒ, the set of points x in the domain of ƒ for which ƒ(x) = y. For a subset A of the range of a function ƒ, the set of points x in the domain of ƒ for which ƒ(x) is a member of A. Also known as inverse image.
Who is the father of goemetry?
Euclid of Alexandria
In a dilation the image is always similar to its pre-image?
Yes, it is.
What is true about every rotation?
The image and pre-image are congruent.
What transformation is not an isometry?
Dilation - the image created is not congruent to the pre-image
What type of transformation are the pre-image and the image congruent figures?
isometry
What is true about every rotation in Geometry?
The image and pre-image are congruent.
When an object is translated is its image is the same size as the pre-image?
true.
What do positive and negative sign of magnification indicate?
Positive would be more magnification, and negative would be less magnification. * * * * * No. M > 1 indicates that the image is bigger than the pre-image (and on the same side of the centre of magnification); 0 < M < 1 indicates that the image is smaller than the pre-image (and on the same side of the centre of magnification); -1 < M < 0 indicates that the image is smaller than the pre-image (and on the opposite side of the centre of magnification); M < -1 indicates that the image is larger than the pre-image (and on the opposite side of the centre of magnification). M = 0 means the image is point-sized and at the centre of magnification. M = 1 means the image coincides with the pre-image. M = -1 means that the image is the same size as the pre-image and on the opposite side.
Who invented coordinate goemetry?
It was conceived by the French mathematician Rene Descartes.
What is an image in math?
It is the output of a function.A function is a mapping that associates an image to each pre-image. The term is often used in the context of transformations but need not be restricted to that use.It is the output of a function.A function is a mapping that associates an image to each pre-image.

A transformation where a pre-image is flipped is called a what?
a reflection
When a figure is translated on a coordinate grid what conclusion can you draw from the pre image and image?
That the image has moved in the same direction and distance of its outline
