A reflection
is a type of transformation that flips a figure over a line. The line is called the line of reflection, or the mirror line. The line of reflection can be horizontal, vertical, or diagonal.
Which rigid transformation means to flip a figure over a line?
A reflection
is a transformation that turns a figure into its mirror image by flipping it over a line. The line of reflection is the line that a figure is reflected over.
Which transformation flips a preimage across a line?
A reflection
is an example of a transformation that takes a shape (called the preimage) and flips it across a line (called the line of reflection) to create a new shape (called the image).
Is a transformation in which the figure flips over a line or segment?
A reflection
is a transformation that turns a figure into its mirror image by flipping it over a line. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the preimage.
What is a flip transformation called?
Flip (
reflection
) — a transformation creating a mirror image of a figure on the opposite side of a line. A flip is also called a reflection. Turn (rotation) — the transformation that occurs when a figure is turned a certain angle and direction around a point. A turn is also called a rotation.
What are the three types of rigid transformation?
There are three basic rigid transformations:
reflections, rotations, and translations
. There is a fourth common transformation called dilation.
How do you tell if a transformation is an isometry?
A geometry transformation is either rigid or non-rigid; another word for a rigid transformation is “isometry”. An isometry, such as a
rotation, translation, or reflection, does not change the size or shape of the figure
. A dilation is not an isometry since it either shrinks or enlarges a figure.
Is the original figure in a transformation?
A transformation can be a translation, reflection, or rotation. A transformation is a change in the position, size, or shape of a geometric figure. The given figure is called
the preimage (original)
and the resulting figure is called the new image.
What is the rule for reflection over the line y x?
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line
y = -x, the x-coordinate and y-coordinate change places and are negated
(the signs are changed). the line y = x is the point (y, x).
What are the three types of transformation?
- Translation happens when we move the image without changing anything in it. …
- Rotation is when we rotate the image by a certain degree. …
- Reflection is when we flip the image along a line (the mirror line). …
- Dilation is when the size of an image is increased or decreased without changing its shape.
What's the rule for transformation?
The function translation / transformation rules:
f (x) + b shifts the function b units upward
. f (x) – b shifts the function b units downward. f (x + b) shifts the function b units to the left.
What are the 5 transformations?

What is the mathematical term for flip upside down?
The reciprocal
of a number is this fraction flipped upside down. In other words, the reciprocal has the original fraction's bottom number—or denominator—on top and the top number—or numerator—on the bottom. So the reciprocal of 6 is 1/6 because 6 = 6/1 and 1/6 is the inverse of 6/1. Below, you can see more reciprocals.
Is Flip a reflection?
A flip is a motion in geometry in which an object is turned over a straight line to form a mirror image. Every point of an object and the corresponding point on the image are equidistant from the flip line. A flip is also called a
reflection
.
What transformation is Y X?
Reflection
in y = x: When you reflect a point across the line y = x, the x-coordinate and the y-coordinate change places. Reflection in y = -x: When you reflect a point across the line y = -x, the x-coordinate and the y-coordinate change places and are negated (the signs are changed).
