9-1 Reflections Vocab Reflection: A transformation that flips a shape Line of reflection: The line over which the reflection is performed

Reflections Over A Line Ex 1: Reflect A (0,3) B (-2, -1) C (-6,1) over the line x = -4 Ex 2: Now reflect it over y = 2

Reflections Over an Axis If you reflect over the x axis, change the sign of y If you reflect over the y axis, change the sign of x Ex 3: Reflect △DEF with D(–2, –1), E(–1, 3), F(3, –1) in the x-axis Ex 4: ABCD with A(1, 4), B(3, 2), C(2, –2), D(–3, 1) in the y-axis
