Transformations

What kind of transformation is this? 

• Translation
• Reflection
• Rotation
• Dilation

This figure has been reflected about...

• the x-axis
• the y-axis
• y = x
• y = -x

Which of the following letters does NOT have two lines of symmetry?

• H
• M
• X
• O

If we rotate a figure 180 degrees and the image is identical to the pre-image, the figure has...

• rotational symmetry
• line symmetry
• point symmetry
• alpha symmetry

An isometry is a transformation in which the pre-image and image of the figure in question are...

• congruent
• similar
• perpendicular
• isosceles

Which of the following is NOT an isometry?

• Reflection
• Dilation
• Rotation
• Translation

You reflect the point (3, 4) about the line y = -x. At what point do you arrive? 

• (-3, -4)
• (-4, -3)
• (3, -4)
• (-3, 4) 

Which of the following is a line of symmetry for rectangle ABCD?

• x = 2
• y = 2
• x = 5
• y = 5

Triangle ABC is reflected across the x-axis and then across the line x = -1.  What are the new coordinates of point C?

• (-5, 1)
• (1, -1)
• (1, -3)
• (0, -4)

Triangle ABC has coordinates a (0, 4), B (1, 3), C(-2, 4).  If triangle ABC is reflected over the x-axis and then translated such that (x, y) becomes (x+3, y-1), what is the resulting image of point C?

• (1, -5)
• (-2, -4)
• (3, -5)
• (4, -4)
