a transformation that moves each point of a figure the same distance and in the same direction
What is a translation AKA slide!
a transformation that flips a figure over a line
What is reflection
A counterclockwise rotation of 90° is the same as how many degrees of rotation clockwise?
270 degrees
P (-5, 1) is translated 6 units to the right and 3 units down the coordinates for P'
What is (1,-2)
the line a figure is reflected over
What is the line of reflection
Triangle B is rotated 270° clockwise with the origin as the center of rotation to create a new figure. What rule describes this transformation?
(x,y)→(-y,x)
A point is translated 8 units to the left and 6 units up. If the preimage point was located at (3, -8) where will the image be located.
Where is (-5, -2)?
Point (2, -7) was reflected over the x axis, where is now located?
(2, 7)
What is the mirror line of a reflection called
LINE OF SYMMETRY
A point about which a figure is rotated
Centre of rotation
G (-2,1) --> G' (4,-5) F (-5,4) --> F' (_,_)
What is (1,-2)
A (3,1) is reflected over the Y-Axis -What is A'
What is (-3,1)
KLMN is dilated to a scale factor of 2 K ( -4,1) --> K' (_,_)
What is (-8,2)
If the coordinates of point P are (2, -3) and then rotated 90 degrees clockwise, what are the new coordinates of point P.
(-3,-2)
The coordinates of triangle JRB are ,J(1, -2) , R(-3, 6) and B(4, 5) . What are the coordinates of its image after the transformation (x, y) ->(x+2, y-1) then reflect over the y-axis
J"(-3, -3), R"(1, 5), B"(-6, 4)
What is the ordered pair for the final location of
P( 2, 3) after this series of transformations? (x,y)→(x+2, y−4) then reflected over the y-axis?
P′(−4, −1)
You are using a magnifying glass. Use the length of the insect and the magnification level to determine the length of the image seen through the magnifying glass.
Original length = 60mm
Magnification= 5 X
300 mm
Which transformation is not considered a rigid transformation
Dilation
What is the ordered pair for the final location of P( -7, 3) after this series of transformations?
(x,y)→(x, y+3) then rotated 90° clockwise about the origin.
P′(6, 7)
