Question

reflect the figure over the line x = 1. plot all of the points of the reflected figure. you may click a plotted point to delete it.

Explanation:

Step1: Recall reflection formula

For a point $(x,y)$ reflected over the vertical line $x = a$, the new - $x$ coordinate is $2a - x$ and the $y$ - coordinate remains the same. Here $a = 1$.

Step2: Apply formula to each point

Let the original points of the figure be $(x_i,y_i)$. The reflected points will be $(2\times1 - x_i,y_i)=(2 - x_i,y_i)$. Calculate the new $x$ and $y$ coordinates for all vertices of the polygon and plot them.

Answer:

Plot the points obtained by using the transformation $(x,y)\to(2 - x,y)$ for each vertex of the given polygon.
