Geometry // Unit test 2

Is the transformation an isometric transformation? Explain.

No, the side lengths are not preserved.

The function rule T-4, 6(x, y) could be used to describe which translation?

a trapezoid on a coordinate plane that is translated 4 units to the left and 6 units up

Which rule was used to translate the image?

(x, y) → (x + 8, y - 11)

Square RSTU is translated to form R'S'T'U', which has vertices R'(-8, 1), S'(-4, 1), T'(-4, -3), and U'(-8, -3). If point S has coordinates of (3, -5), which point lies on a side of the pre-image, square RSTU?

-1, -6

Triangle PQR has vertices , , and . It is translated according to the rule .
