7.1 Rigid Motion in a Plane. Objectives/Assignment. Identify the three basic rigid transformations Assignment: 2-38 even. Identifying Transformations. Figures in a plane can be Reflected Rotated Translated To produce new figures. The new figures is called the IMAGE .
Rotation about a point
Reflection in a line
The cordinates of the vertices of the image, ∆A’B’C’, are A’(4,1), B’(3,5), and C’(1,1).Example 1: Naming transformations
The order in which the vertices are listed specifies the correspondence. Either of the descriptions implies that
A D, B E, and C F.Mappings
