Triangle ABC is reflected over the y-axis to form triangle A’, B’, C’.
What are the coordinates of C’?
the cords of C is either 1,3 or 3,1
no idea, but this kind of reflection takes (x,y)→(-x,y)
To find the coordinates of point C’ after reflecting triangle ABC over the y-axis, you need to apply the reflection operation.
The reflection operation for the y-axis involves changing the sign of the x-coordinate while keeping the y-coordinate unchanged.
Let's say the coordinates of point C in triangle ABC are (x, y). To find the coordinates of C’ after reflecting over the y-axis, you simply change the sign of the x-coordinate and keep the y-coordinate the same.
So, the coordinates of C’ would be (-x, y).
