What is the LINE OF REFLECTION?
or
What is the MIRROR LINE?
100
The image of triangle ABC when A(1,1), B(2,3), and C(4,6) if it is translated by the rule (x,y) ---> (x-4,y+2) lies here.
What is A'(-3,3), B'(-2,5), and C'(0,8)?
100
The distance all pre-image points and their respective image points are from the line of reflection.
What is EQUAL?
100
The angle of rotation shown in the rule
(a,b) ---> (-b,a).
What is 90 DEGREES COUNTERCLOCKWISE?
200
The figure after the transformation
What is the IMAGE?
200
The point that a rotation is turned about.
What is the CENTER OF ROTATION?
200
The image of point G(5,7) after it translates along the vector <7,-2>.
What is G'(12,5)?
200
Points that are on the line of reflection always reflect to here.
What is ON THE LINE OF REFLECTION?
200
The angle of rotation between point D and D' in parallelogram ABCD if point A rotates 35 degrees to point A'.
What is 35 DEGREES?
300
A transformation across a line. Each point travels on a path perpendicular to the line. Also, each point and its image are the same distance from the line.
What is a REFLECTION?
300
Two or more figures that have the same size and shape.
What is CONGRUENT?
300
The vector if A(10,3) ----> A'(7,15).
What is <-3,12>?
300
The line of reflection represented by the rule
(x,y) ---> (x,-y).
What is THE x-AXIS?
300
The point W' after a 180 degree rotation about the origin if point W(-3,8).
What is W'(3,-8)?
400
A transformation about a point P. Each point and its image are the same distance from P.
What is a ROTATION?
400
A transformation that does not change the shape or size of a figure.
What is an ISOMETRY?
400
The vector that is the same as the translation rule
(x,y) ---> (x-2,y+7).
What is <-2,7>?
400
The line of reflection represented by the rule
(x,y) ---> (-x,y).
What is THE y-AXIS?
400
The pre-image point Q if Q'(-4,-5) after a 180 degree rotation about the origin.
What is Q(4,5)?
500
A transformation in which all the points of a figure move the same distance and in the same direction.
What is a TRANSLATION?
500
The rule that rotates a figure 90 degrees counterclockwise.
What is (a.b) ----> (-b,a)?
500
The pre-image of R'(13,8) if the vector of translation was
<4,3>.
What is R(9,5)?
500
The line of reflection represented by the rule
(x,y) ---> (y,x).
What is THE LINE y=x?
500
The image of K(9,-5) after a 450 degree counterclockwise rotation about the origin.
