Detailed description
Cartesian plane shown with two triangles ABC and \(A^\prime B^\prime C^\prime\) and a point D. Dashed lines joining A to D and then D to \(A^\prime\), B to D and then D to \(B^\prime\) and from C to D and then from D to \(C^\prime\).
Coordinates:
D(7, 6); A(4, 4); B(3, 6); C(5, 7)
\(A^\prime(9, 3)\); \(B^\prime(7, 2)\); \(C^\prime(6, 4)\)
