What point of transformation does not move in isometry?
In an isometry, the point of transformation that does not move is called the "fixed point." This point remains unchanged during the transformation, whether it is a translation, rotation, or reflection. For example, in a rotation, the center of rotation serves as the fixed point, while in a reflection, the line of reflection equidistantly bisects the space, with points on the line remaining unchanged.
Give an example of reflection?
Geometry reflection: a flip of a figure over a specific point or line Real life situation: mirror or reflecting pool.
What are glide reflection and rotational transformations?
A glide reflection is a combination of a reflection in a line and a translation along that line. This can be done in either order. A rotational transformation is a rotation around a fixed point or axis.
Which transformation turns every point of the preimage through a specified angle and direction about a fixed point?
A rotation turns a shape through an angle about a fixed point
What is point in geometry?
A point is a vertex

What is the transformation called when you flip a figure in a mirror line?
The transformation is called a reflection. In a reflection, each point of the figure is mapped to a corresponding point on the opposite side of the mirror line, maintaining the same distance from the line. This creates a mirror image of the original figure.
What transformation could be used to transform a point at 4 2 to a point at -4 2?
A reflection or a 'mirror image' in the y axis

A point of a transformation is a point that does not move.?
In the context of transformations, a point that does not move is often referred to as a fixed point. This means that when a transformation, such as rotation, reflection, or translation, is applied, the fixed point remains unchanged in its position. Fixed points are important in understanding the behavior of various transformations and can serve as reference points for analyzing the effects of the transformation on other points in the space.
What is the difference between rotation and reflection in graphic design?
Rotation is a transformation that spins an object on a specific point. In Adobe Illustrator, an object's default rotation point is its centre.Reflection is a transformation that flips an object over and across a specific axis. In Adobe Illustrator, an object's default reflection axis runs vertically through its centre.
What is a rotation, and how does it relate to the transformation of an object?
A rotation is a transformation that turns an object around a fixed point. It changes the orientation of the object without changing its shape or size. Rotations are a type of transformation that can be applied to objects in geometry to change their position or direction.
How do you determine the coordinates of a point after a reflection in the you axis?
To determine the coordinates of a point after a reflection in the y-axis, you simply negate the x-coordinate while keeping the y-coordinate the same. For a point with coordinates ((x, y)), its reflection across the y-axis will be at ((-x, y)). This transformation effectively flips the point over the y-axis, maintaining its vertical position but reversing its horizontal position.
What is a type of transformation where an original figure is flipped over a line onto its image?
A type of transformation where an original figure is flipped over a line onto its image is called reflection. In this process, each point of the original figure is mapped to a corresponding point on the opposite side of the line, maintaining equal distance from the line of reflection. This creates a mirror image of the original figure.
What is the rule for a reflection across the origin?
To reflect a point across the origin, you simply change the sign of both the x- and y-coordinates of the point. This transformation involves multiplying the coordinates by -1.
