Detailed description
Cartesian plane shown with two triangles ABC and \(A^\prime B^\prime C^\prime\). Dashed lines joining A to \(A^\prime\), B to \(B^\prime\) and C to \(C^\prime\). These lines cross the x axis at X, Z and Y.
Coordinates:
A(1, 1); B(4, 2); C(2, 4)
\(A^\prime(1, –1)\); \(B^\prime(4, –2)\); \(C^\prime(2, –4)\)
