Translation
what is a translation ?
the moving of a point on a coordinate plane
what are the coordinates after a reflection across the origin from (1,1)
(-1,-1)
which direction do you always rotate, unless otherwise stated?
clockwise
what is a dilation ?
a dilation is the growing or shrinking of a shape
WHAT IS THE RULE FOR (1,1) TO (2,2)
(X+1,Y+1)
what is the definition of a reflection
a reflection is when a point is mirrored over a line or point on the coordinate plane
if (x,y) is rotated 90 degrees what is the outcome?
(-y,x)
what is the thing used to determine the size of the image?
a scale factor
is the rule for a translation always the same?
no
What is the final coordinates after (x,y) is reflected over the y axis?
(-x,y)
WHAT IS THE RULE FOR ROTATING 180 DEGREES?
(-x,-y)
if i used a scale factor of 2 how much bigger would the shape get?
twice the size
starting at the origin if you add 5 to x and 12 to y what are your new points
(5,12)
what is the rule for a reflection across the x axis?
(x,y) to (x,-y)
what is rotation ?
a "spin" of a point or shape around a point
if i used a scale factor of 1 would the shape get bigger or smaller?
it would stay the same size
starting at the origin what is (x+-9,y-3)
(-9,-3)
if (x,-y) is reflected across the origin what is the ending coordinate?
(-x,y)
if you rotated (x,y) 360 degrees what would you get?
(x,y)
if the scale factor going from the smaller shape to the bigger shape is 10, then what is the scale factor going from the bigger shape to the smaller shape?
1/10
