Final Jeopardy
Know the Rules!
$200 Answer Definitions
A transformation where all points are moved the same distance in the
same direction
$1000 Answer Definitions
The number of times the figure coincides with itself as
it rotates through 360o
$200 Question Transform It!
Point A is at (4, -5).Find A’ after a translationalong the vector <-6, 4>.
$600 Question Transform It!
Point A is at (8, -2).Find A’ after a rotation by 90°
counterclockwiseabout the origin.
$800 Question Transform It!
Point A is at (3, -6).Find A’ after a dilation of -1/3
about the origin.
$1000 Question Transform It!
Point A is at (3, -6).Find A’ after a reflection over
the line y = -x and then a translation along the vector
<-4, -4>.
$400 Answer Know the Rules!
90° clockwise rotation OR 270° counterclockwise rotation about the origin
$800 Question Know the Rules!
Write the rule you would use to find the image
coordinates of (x, y) under a translation of 2 units right
and 1 unit down.
$1000 Question Know the Rules!
Write the rule you would use to find the image coordinates of (x, y) under a dilation with scale factor = -1 followed by
180° rotation about the origin.
$400 Question Potpourri
Does the figure have rotational symmetry? If so, give the angle of rotational symmetry and the order
of symmetry.
$600 Question Potpourri
A translation can be interpreted as successive
reflections across two lines. Tell what relationship the lines must have for this to be true.
$800 Question Potpourri
The pre-image is (10, -8), the image is
(2, -4). What is the translation vector?
$1000 Question Potpourri
What is the scale factor of a dilation centered at the origin that maps A(5, -6)
to A’(-15.5, 18.6)?
Final Jeopardy
A hiker walks 2 miles east and then 1 mile north, then hikes 4 miles east and sets
up camp. What vector describes their hike from their starting position to
their camp?
