Rflection of a triangle

This lab shows the reflection of a triangle in the cartesian coordinate system. To reflect the triangle move points m and/or b. To change triangle move points A, B or C
Compute the following isometric reflection on paper then verify your answer using the applet above.[br][br]Given triangle A(1,3) B(2,2) and C(3,3)[br][br]a. Reflect over x axis[br]b. Reflect over y axis[br]c. Reflect y = x[br]d. Reflect y = -x
