X- Axis Reflection
T(x, y) → T'(x, -y)
Y-Axis Reflection
T(x, y) → T'(-x, y)
Move left 5, up 2 units
T(x, y)→ T'(x-5, y+2)
Move right 10, down 8 units
T(x, y)→ T'(x +10, y-8)
90° Clockwise Rotation (270° Counterclockwise)
T(x, y) → T'(y, -x)
180° Clockwise Rotation
T(x, y) → T'(-x, -y)
270° Clockwise Rotation (90° Counterclockwise)
T(x, y) → T'(-y, x)
360° Clockwise Rotation
T(x, y) → T'(x, y)
Dilate with a scale factor is 75%?
T(x, y) → T'(.75x, .75y)
If theDilate with a scale factor f 250%?
T(x, y) → T'(2.5x, 2.5y)
Dilate with a scale factor is 3?
T(x, y) → T'(3x, 3y)
Dilate with a scale factor is ½?
T(x, y) → T'(.5x, .5y) or (½x, ½y)
Dilation
a transformation that reduces and enlarges a figure from its original size
Rotations
a transformation that turns a figure about a point in either clockwise or counterclockwise direction
Translation
Slides every point the same distance and direction
Reflections
flips an image over a line called a line of reflection
90° Counterclockwise Rotation (270° Clockwise)
T(x, y) → T'(-y, x)
