Similarity Transformations

D'(2,6)

D'(4,3)

D'(-2,-3)

D'(2,3)

Isometric transformations have the same shape AND size, similarity transformations just have the same shape.

Isometric transformations are cooler

Isometric transformations have the same shape AND size, similarity transformations just have the same size.

They are the same, no differences.

Quad OBCD can be reflected over the x axis and then rotated 90 degrees

Quad OBCD can be reflected over the x-axis and then dilated about point O by a scale factor of 2.

Quad OBCD can be reflected over the y-axis and then dilated about point O by a scale factor of 2.

Quad OBCD can be reflected over the y-axis and then dilated about point O by a scale factor of 1/2.

ΔOBC can be dilated about point O by a scale factor of 1/2, and then rotated 90 degrees about point O.

ΔOBC can be dilated about point G by a scale factor of 1/2, and then reflected over the x- axis

They aren't similar

They map to each other with similarity transformations.
