{{ printedBook.courseTrack.name }} {{ printedBook.name }} To rotate the polygon about point $P,$ we will rotate each vertex of the polygon about point $P.$ Let's begin with vertex $B.$ We will first draw a segment from $B$ to $P.$

Next, we will draw a $45_{∘}$ angle using $PB.$ Since the direction of the rotation isn't stated, we will assume that it is counterclockwise.

Now, we will use a ruler to draw $B_{′}$ such that $PB=PB_{′}.$

By repeating the process for vertices $C$ and $A,$ we can draw $△A_{′}B_{′}C_{′}.$

Finally, we will remove the unnecessary elements to see $△A_{′}B_{′}C_{′}.$
