Types of transformations
LESSON 4-7 Congruence Transformations
Preimage original figure
Translation or slide moves all the pts the same
distance in the same direction
Reflection or flip over a line called the line
of reflection
Rotation or turn around a fixed point called
the center of rotation

LESSON 4-7 Congruence Transformations
Identify Congruence Transformations
EXAMPLE 1 2
Identify the type of congruence transformation
shown as a reflection, translation, or rotation.

Example 3
LESSON 4-7 Congruence Transformations
Verify Congruence after a Transformation
EXAMPLE 1 2
Triangle PQR with vertices P(4, 2), Q(3, 3), and
R(5, 2) is a transformation of ?JKL with
vertices J(2, 0), K(3, 5), and L(1, 4).
Graph the original figure and its image. Identify
the transformation and verify that it is a
congruence transformation.
