Identifying Rigid Transformations

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

• (x, y) -> (x+8, y+4)

• (x, y) -> (x+ -8, y-4)

• (x, y) -> (x+4, y+8)

• (x, y)->(x+ -4, y+ -8)

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

• 5 units down and 5 units to the right

• 5 units down and 1 to the right

• 8 units down and 5 units to the right

• 5 units down and 4 units to the right

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

• 90^o clockwise rotation

• 90^o counter clockwise rotation

• Reflection across the y-axis

• Reflection across the x-axis

• clockwise

• counterclockwise

• counterclockwise

• clockwise

This type of transformation moves every point on a figure to a point directly on the opposite side of a line. The new point is the same distance from the line as it was in the original figure.
