 Practice - Sequence of Transformations Terms of Use    Contact Person: Donna Roberts  1. Does this fish
illustration depict
a glide reflection?

 yes no

2.

The point (3,−2) is rotated 90º about the origin and then dilated by a scale factor of 4. What are the coordinates of the resulting image?

Choose:
 (-12,8) (12,-8) (8,12) (-8,-12)

3. Is ΔA''B''C''
a glide reflection
of Δ ABC?

 yes no

4. ΔADE is the image of ΔABC after a reflection over the line through points A and C, followed by a dilation of scale factor ½ centered at point A.
Which statement must be true?

Choose:
 m∠BAC = m∠AED m∠ABC = m∠ADE m∠DAE=½ • m∠BAC m∠ACB = ½ • m∠DAB

5. Does this paw print illustration depict a glide reflection?

 yes no

Which transformation sequence does NOT depict this change?

Choose:
 reflection over x-axis, then translation 5 units left reflection over x-axis, then reflection over y-axis translation 5 units left, then reflection over x-axis

9.
Given ΔABC with A(1,1), B(2,3) and C(3,1). If ΔA'B'C' is the result of a reflection in the y-axis, followed by a dilation of scale factor 2 centered in the origin, then ΔA'B'C' is ...
Choose:
 similar to ΔABC congruent to ΔABC neither similar nor congruent to ΔABC 10.
