Common Properties of Rotations, Reflections, and Translations Rotations - Have you ever turned the handle of a door? The action that you performed is called rotation. In math, rotation is the same! In simple words, rotation is anything that changes its position around a fixed axis or point. - Rotation moves line to line, segment to segment, rays to rays, angles to angles, parallel lines to parallel lines - Rotation preserves the segment's length and degrees to the measure of an angle is similar to the translation. - Rotation requires more than one piece of information Translations - When you slide something across the table, then it means that you have performed an action that is called translation. In the process of translation of an object along (x,y) coordinates, one of the axes will remain constant. For example, shifting books on a bookshelf 18 inches to the left. As the movement is horizontal, the y-axis will remain constant. Reflection - As the name suggests, it is a movement that causes the shape of an object to flip across the same line. It is the same process that is caused by the mirror. The shape is drawn usually on a 2D coordinate (x,y) These worksheets and lessons have students reflect, rotate, and translate objects, shapes, and points using a coordinate grid system.

Homework Sheets

Time to jump our points all over the place.

  • Homework 1 - Graph the image of B(3, 3) after a translation 4 units down. First we have to start with the point B (3, 3). Then we should move 4 units down.
  • Homework 2 - Reflections are a transformation where one figure is the mirror image of another.
  • Homework 3 - We also know that 180┬░ is 1/2 of a full turn. So, the rotation will turn the point 1/2 of a full turn in the clockwise direction.



Practice Worksheets

We focus on one of the major topics on each sheet.

  • Practice 1 - Graph the image of P (-6, 4) after a reflection over the y-axis.
  • Practice 2 - Graph the image of N (10, 10) after a rotation 270┬░counter clockwise around the origin.
  • Practice 3 - Graph the image of R (-40, -40) after a reflection over the x-axis.



Math Skill Quizzes

It's best to sketch what each question is asking you before you actually plot the points.

  • Quiz 1 - Graph the image of B(4, -4) after a translation 5 units up.
  • Quiz 2 - Graph the image of C (-2, -2) after a reflection over the y-axis
  • Quiz 3 - Graph the image of U (-3, 1) after a rotation 90┬░ counter clockwise around the origin.
