Question

1 reflect over the x - axis. click to select polygon abc

Explanation:

Step1: Recall reflection rule

The rule for reflecting a point $(x,y)$ over the x - axis is $(x,-y)$.

Step2: Assume coordinates of points

Let's assume $A=(x_1,y_1)$, $B=(x_2,y_2)$, $C=(x_3,y_3)$. After reflection over the x - axis, the new points will be $A'=(x_1,-y_1)$, $B'=(x_2,-y_2)$, $C'=(x_3,-y_3)$.

Step3: Plot new points

Plot the points $A'$, $B'$, $C'$ and connect them to form the reflected polygon $A'B'C'$.

Answer:

Plot the points obtained by changing the sign of the y - coordinates of the vertices of polygon $ABC$ and connect them to form polygon $A'B'C'$.
