perpendicular lines, Lesson 2.3 Checkpoint Once you have completed the above problems and checked your solutions, complete the Lesson Checkpoint below. Complete the Lesson Reflection above by circling your current understanding of the Learning Goal. 1. Draw the image of the figure under the given rotation. Make sure to label appropriately. Quadrilateral PQRS; 270 about the origin. 2- X -4 -2 0 2 4 S 0 R 2. Write the coordinate notation for the following: Transformation Rule: (x,y) Preimage Coordinates (x, y) Image Rules for Rotation on a Coordinate Plane Coordinate Notation 90 rotation counterclockwise 180 rotation 270 rotation counterclockwise 360 rotation 3. Are all rotations considered a rigid motion? Explain why or why not by explaining its effects on a figure's angles and line segments.
