If the figure is reflected across the line x = –2 and a translation 3 units up, the new points is at A'(-5, 4), B'(-5, 7), C'(-8, 7) and D'(-8, 4).
What is transformation?
A transformation is a function f, usually with some geometrical underpinning, that maps a set X to itself, i.e. f: X → X.
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, translation, rotation and dilation.
Figure ABCD has vertices A(1, 1), B(1, 4), C(4, 4), and D(4, 1). If the figure is reflected across the line x = –2 and a translation 3 units up, the new points is at A'(-5, 4), B'(-5, 7), C'(-8, 7) and D'(-8, 4).
