Section Name: Reflections Warm-up What kind of transformation is below? Is this transformation isometric? Write a congruency statement. Name a pair of congruent sides. Name a pair of congruent angles. Which is the image and which is the pre-image? Section Name: Reflections

Reflect TACK across the line x=0 Are segments in TACK and their images in T’A’C’K’ the same length? How do you know? Are the angles in TACK and their images in T’A’C’K’ the same measurement? How do you know? Are TACK and its image T’A’C’K’ congruent?

Reflect TACK across the line y=x

Reflect FIN across the line y=1

Reflect FIN across the line y=-x

Reflect FIN across the line x= -1
