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 a figure formed by a transformation?
A transformation can be several changes.A translation is a slide without changing the figure.A rotation is a turn around a point that doesn't change the figure.A dilation is a change in size either larger or smaller.A reflection is a flip over a line that doesn't change the size.

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

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 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.
What is the term of geometry for Point lines and planes?
Point, line and plane ARE terms from geometry.
What is point in geometry?
A point is a vertex
What is the 'normal' to a surface?
The normal to a surface is an imaginary line that is perpendicular to the surface at a specific point. It indicates the direction that is perpendicular to the surface and is used in geometry and physics to determine angles of incidence and reflection.
What is a figure formed by a transformation?
A transformation can be several changes.A translation is a slide without changing the figure.A rotation is a turn around a point that doesn't change the figure.A dilation is a change in size either larger or smaller.A reflection is a flip over a line that doesn't change the size.
A figure is transformed in the plane such that no point maps to itself. What type of transformation?
It could be a reflection with the mirror line outside the figure; it could be a rotation with the centre of rotation outside the figure; or it could be a translation.
What are the 3 unedifying terms in geometry geometry?
Point ; Line ; Plane - Remember the Point-Line-Plane Postulate
