Translations and Reflections - Review #1

Which point represents a reflection of point A(9, -2) over the x-axis?

• (-2, 9)

• (9, -2)

• (9, 2)

• (-9, -2)

The rule for translating a figure 3 units left and 5 units down can be expressed as

• (x + 5, y - 3)

• (x - 5, y + 3)

• (x - 3, y + 5)

• (x - 3, y - 5)

Identify the transformation from ABCD to A'B'C'D'.

• Translation 7 units to the left

• Reflection across the y-axis

• Reflection across the x-axis

• Reflection of y = x

Identify the transformation from ABC to A'B'C'.

• T_8,4

• T-_8,-4

• T_4,8

• T_-4,-8

State the line of reflection.

• Reflection over the y-axis

• Reflection over the x-axis

• Reflection over the line y = x

• Reflection over the line y = -x

True or False?

When a figure is reflected over a line of reflection, the new image is congruent to the original.

• True

• False

True or false?

When a point is reflected across a line of symmetry, it remains the same distance from the line.

• true

• false

What are the coordinates of B(-2, -4) after being reflected over the line y = x?

• (-4, 2)

• (-4, -2)

• (4, 2)

What was the line of reflection?

A(4, 8) --> A'(8, 4)

• x-axis
