Coordinate Geometry Transformations

How is trapezoid ABCD translated to trapezoid A'B'C'D'?

• Translated 8 units down and 5 units to the right

• Translated 5 units down and 4 units to the right

• Translated 5 units down and 5 units to the right

• Translated 5 units down and 1 to the right

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

• 90^o counterclockwise rotation

• Reflection across the x-axis

• Translation

• 90^o clockwise rotation

What is the rule for the translation?

• (x -2, y + 1)

• (x +2, y - 1)

• (x +1, y - 2)

• (x -1, y + 2)

• (4, 1))

• (-1, -4)

• (1, -4)

• (1, 4)
