Question

question 1 - 2
if triangle abc is reflected over the y - axis, which point(s) will remain the same?
none of the points
point c only
point b only
point b and c

Explanation:

Step1: Recall reflection rule

When a point $(x,y)$ is reflected over the $y -$axis, the transformation is $(-x,y)$. Points on the $y -$axis have an $x -$coordinate of 0. After reflection over the $y -$axis, points with $x = 0$ will remain in the same position since $-(0)=0$.

Step2: Identify point on y - axis

We need to find which point of $\triangle ABC$ lies on the $y -$axis. By observing the graph, we can see that point $B$ lies on the $y -$axis.

Answer:

Point B only
