QuestionFind the new coordinates of vertices B $(2,-9)$, C $(2,-4)$, and D $(1,-9)$ after a $270^{\circ}$ clockwise rotation.

Studdy Solution
Calculate the new coordinates of vertex D.
$$(x'_, y'_) = (9, -)$$The coordinates of the vertices B, C, and D after a rotation of $270^{\circ}$ clockwise around the origin are B $(9, -)$, C $(4, -)$, and D $(9, -)$.
