dilation, similar figures, transformation
TEKS 8(1)(D), 8(1)(F), 8(1)(G), 8(10)(A)
A two-dimensional figure is similar to another two-dimensional figure if you can map one figure to the other by a sequence of rotations, reflections, translations, and dilations.
The symbol ∼ means “is similar to.”
Suppose you start with rectangle ABCD and translate it 6 units to the left and 1 unit up.
Rotate it 90 degrees about the origin.
