Question

Please write the coordinates of the vertices after a 180 degrees rotation clockwise around the origin coordinates only please

Answer 1

Solution

Given a triangle DEF of the following vertices

$\begin{gathered} D(-5,2) \\ E(-3,2) \\ F(-1,9) \end{gathered}$

To find the vertices of the triangle after a 180 degrees rotation clockwise around the origin, we apply the rule below

$(x,y)\rightarrow(-x,-y)$

Hence, the vertices of the triangle after a 180 degrees rotation clockwise around the origin will be

$\begin{gathered} D(-5,2)\rightarrow D^{\prime}(5,-2) \\ E(-3,2)\rightarrow E^{\prime}(3,-2) \\ F(-1,9)\rightarrow F^{\prime}(1,-9) \end{gathered}$
