Create and Prove Congruence
Rigid Motions on the Coordinate Plane
Create a congruent copy of a polygon using a written sequence of rigid motions, record coordinates at every step, and verify congruence using measurements.
Part A — Choose a Pre-image[br][br]1. Choose one polygonal feature from the graph below.
2. Record the pre-image coordinates clearly below.[br][br]Vertex Coordinates:
3. Find the image on the graph for your chosen pre-image.
Describe a congruence transformation that maps the pre-image onto the image.
4. Record the coordinates of the transformed image.
