100
A transformation
What is an operation that maps, or moves, a figure?
100
A transformation which uses a line which acts like a mirror.
What is a reflection?
100
A transformation in which a figure is turned about a fixed point.
What is a rotation?
100
A transformation where every point P is mapped on to the point P'
What is a translation?
100
A transformation in which every point maps P to P" by first a translation that maps P to P' then a reflection in a line parallel to the translation that maps P' to P".
What is a glide reflection?
200
The original figure.
What is the preimage?
200
The mirror line.
What is the line of reflection?
200
The center of rotation.
What is the fixed point?
200
Translations in a coordinate plane can be described by this notation.
What is (x,y) mapped to (x+a, y+b)?
200
When two or more transformations are combined to produce a single transformation.
What is a composition?
300
The new figure that has been transformed
What is the image?
300
A figure has this if it can be mapped onto itself by a reflection in that.
What is the line of symmetry?
300
A figure in the plane has this if the figure can be mapped onto itself by a rotation of 180 degrees or less.
What is rotational symmetry?
300
A quantity that has both a direction and magnitude and can be represented by an arrow drawn between two points.
What is a vector?
300
A transformation that preserves lengths, angles and measurements of its preimage.
What is an isometry?
400
To turn the figure.
What is a rotation?
400
The number of lines of symmetry in a square.
What is four lines of symmetry?
400
The angle that the figure is turned.
What is the angle of rotation?
400
Two numbers which represent the units; the initial and final points move horizontally and vertically.
What is the component form?
400
A pattern that extends to the left or right in such a way that the pattern can be mapped onto itself by some type of transformation.
What is a frieze pattern?
500
To flip it.
What is a reflection?
500
The number of lines of symmetry in a parallelogram.
What is 0 lines of symmetry?
500
The 90 degrees clockwise rotation about the origin.
What is (x, y) mapped to (y, -x)?
500
The notation used to write out components. Example: {4,5}.
What is {horizontal component, vertical component}?
500
The number of ways that a frieze pattern can be mapped onto itself by a transformation.
What are 5 ways?
