Question

Unit 3 lesson 11 multiple transformation quick check

Answer 1

1. Which sequence of transformations could be used to map triangle ABC onto triangle A'B'C'?

a. reflection over the x-axis, then translation 3 units left
b. rotation 90 degrees counterclockwise, then reflection over the y-axis
c. dilation by a scale factor of 2, then rotation 180 degrees
d. translation 4 units up, then reflection over the line y=x

2. Which sequence of transformations would result in a figure that is congruent to the original figure?

a. reflection over the x-axis, then translation 3 units left
b. rotation 180 degrees, then reflection over the y-axis
c. dilation by a scale factor of 2, then rotation 90 degrees counterclockwise
d. translation 2 units to the right, then rotation 270 degrees counterclockwise

a. dilation
b. rotation
c. reflection
d. translation

4. True or False: A translation and a rotation are examples of rigid transformations.
