Question

if triangle abc is rotated 90 degrees clockwise about the origin, what are the coordinates of point a? (, -3)

Explanation:

Step1: Recall rotation rule

The rule for a 90 - degree clockwise rotation about the origin is $(x,y)\to(y, - x)$.

Step2: Identify original coordinates of A

From the graph, assume the coordinates of point A are $(3,0)$.

Step3: Apply rotation rule

Using the rule $(x,y)\to(y, - x)$ with $x = 3$ and $y = 0$, we get $(0,-3)$.

Answer:

$(0,-3)$
