1.

Categorize each transformation from polygon A to polygon B as a rigid transformation or a non-rigid transformation.

  • Rigid Transformation
  • Non-rigid Transformation
2.

Draw the stop sign after a horizontal reflection.

3.
Consider the point P with coordinates (-2, 3). If it is translated 3 units left and 5 units up, the coordinates of P' will be (_______ ,_______ ).
4.

Graph point A', B', C', and D' after quadrilateral ABCD has been rotated 90 \degree clockwise. (y, -x)

  • Click the graph tab.
  • Click on the graph background to add a point. Drag a point or type in x and y coordinates to edit its position. Click on a point to delete it.
5.

Which best represents the coordinate pair (x, y) after a 90 \degree clockwise rotation around the origin?

6.

Select a sequence of transformations that will map key K to keyhole K'. Order is not important.
