$1.5.6.$ A flat solid body rotates around an axis perpendicular to its plane. The coordinates of the initial position of points $A$ and $B$ of this body are ($-1$, $2$) and ($3$, $1$), and the final position is ($-3$, $1$) and ($-2$, $-3$). Use a graphical plot to find the coordinates of the rotation axis.
</p>
<h3>Solution</h3>
<p>
<p>Since the axis of rotation is fixed, all points of the body rotate around it and are perpendicular in direction.
</p>
<p>If the coordinates of two points at the beginning and end are $A$, $B$ and $A'$, $B'$ respectively, then if you draw lines $AB$ and $A'B'$, their intersection point will be the center of rotation
