True or False: A dilation is not an isometric transformation.
True - A dilation is not an isometry because it does not preserve the size of the shape.
What is the definition of an image?
Shape after the transformation has been performed
What is the new image of G(8, 10) if it undergoes a dilation by a factor of 25?
G'(200, 250)
What transformations change the direction but not the shape of a figure?
Rotation and Reflexion.
What is the dilation factor if A(-2, 3) mapped to A'(-0.9, 1.35)?
D 0.45
What is the numerical difference between an enlargement of a shape and a reduction?
Enlargement is a dilation by a number bigger than 1, Reduction is a dilation by a number between 0 and 1.
Dilation of factor 1/8 of A(-4, -6.2) B(1/2, 1/3) C(-5, -7)? Leave in the simplest fraction form!
A(-1/2, -31/40) B'(1/16, 1/24) C'(-5/8, -7/8)
What transformation changes the size, but not the direction neither the shape of an image?
Dilation
What is the original image of D'(-8, -12) E'(-8, 12) F'(12, -8) if it underwent a dilation by 2?
D(-4, -6) E(-4, 6) F(6, -4)
What is an isometry, or rigid motion?
Transformation that changes position without changing size or shape of figure.
