Question

b. Triangle DEF with coordinates D(-2, 2), E (1,5), and F (4, -1) is rotated 90° counterclockwise aboutthe origin

Answer 1

`\begin{gathered} D^{}(-2,2) \\ E(1,5) \\ F(4,-1) \\ D´(-2,2) \\ E^(\prime)(-5,1) \\ F(1,4) \\ \text{The new coord}inates\text{ are }D´(-2,2),\text{ }E^(\prime)(-5,1)\text{ and }F(1,4) \end{gathered}`
