Question

drag the tiles to the boxes to form correct pairs.

polygon abcd is rotated 90° counterclockwise about the origin to create polygon abcd. match each set of coordinates to the vertices of polygon abcd.

Explanation:

Identify original coordinates

Using the Geometric Transformations knowledge point

$$
LATEXBLOCK0
$$

Apply rotation rule

Using the Rotations in the Coordinate Plane knowledge point

$$ (x, y) ightarrow (-y, x) $$

Calculate rotated coordinates

Using the Rotations in the Coordinate Plane knowledge point

$$
LATEXBLOCK1
$$

Answer:

Vertex	Coordinates
\(B'\)	\((-2, 1)\)
\(C'\)	\((-2, 2)\)
\(D'\)	\((-1, 3)\)
