Question

rotating a negative number of degrees. which shows the image of triangle wxy after the transformation r₀, - 90° (x, y)?

Explanation:

Step1: Rotation rule for -90°

For a point \((x,y)\), \(R_{O,-90^\circ}(x,y) = (y,-x)\).

Step2: Apply to triangle vertices

Assuming original vertices (common in such problems), transformed coordinates follow \((y,-x)\), shifting the triangle to the first quadrant.

Answer:

[The image corresponding to vertices transformed by \((x,y) \to (y,-x)\)]
