Question

Use the figure for 3-4. 3. If the figure is rotated 90° counterclockwise, in which quadrant will it appear?4. After the rotation, what will be the coordinates of P?

Answer 1

`\begin{gathered} 1-\text{The coordinates of the vertice of the quadrilateral are } \\ (-5,-2) \\ (-7,-4) \\ (-3,-5) \\ (-3,-3) \\ \end{gathered}`
`\begin{gathered} \text{ 2- Remember that when you rotate 90 degrees counter clockwise } \\ \text{ the coordinate (x,y) is mapped to (x,y)---> (-y,x), so each coordinate} \\ \text{ is mapped to :} \\ (-5,-2)--->\text{ (2,-5)} \\ (-7,-4)---->(4,-7) \\ (-3,-5)---->(5,-3) \\ (-3,-3)----->(3,-3) \end{gathered}`
