For parents, there are answer keys provided for each worksheet. Color examples and graphics come with each transformations worksheet, and this helps to keep students engaged as they complete their work. The transformations worksheets that are available through can help to bring these more abstract 8th-grade math concepts into focus.Įach transformations worksheet starts with the basic concept and then build to more complex questions. The good news is students (and parents) don’t have to struggle through the various types of transformations anymore. These are all different type of transformation. Translations, reflections, dilations and rotations all involve some visualization of the problem to be able to figure out the answer. Many geometric concepts also involve being able to visualize certain aspects of a problem. With algebra, there is a set formula and method to solve every problem, but in geometry, there has to be some spatial awareness and knowledge built up to be able to use formulas to solve problems. ![]() Geometry is really a branch based on creativity rather than analysis, and some students have not developed those skills as much. Rotation moves an object around a point.One of the most likely reasons is that this branch of math requires students to use their spatial skills more than their analytical skills.Reflection produces a mirror image of the original figure.Translation occurs when a figure is moved a certain distance in a certain direction.Transformations are changes to the size, shape, location, or orientation of a figure.Choice C shows a reflection, which produces a mirror image of a figure over a line. Choice A shows rotation, which rotates a figure around a given point. A translation is a transformation that slides a figure a certain distance in a certain direction. Which of these is an example of a translation? Polygon with Rotational Symmetry Question This figure can be rotated 120° or 240° and it will appear unchanged. A figure has this property if it can be rotated around a point by less than 360° and the object appears unchanged. The equilateral triangle below has a property called rotational symmetry. The yellow figure has been rotated 215° around point A to produce the orange figure. While the rotation changes the object’s orientation, the rotated image is congruent to the original figure. All regular polygons have bilateral symmetry.Ī rotation is a transformation that rotates an object around a point. In fact, this figure has many lines of symmetry, but only one is drawn here. The figure can be divided in half by a line of symmetry so that one side is a mirror image of the other side. The image below shows a figure that has a property called bilateral symmetry. The yellow figure (left) has been reflected over the dotted line to produce the orange mirror image (right). While the reflection changes the object’s orientation (top and bottom, left and right), the reflected image is congruent to the original figure. ReflectionĪ reflection is a transformation that produces a mirror image of the original figure by flipping it across a line. The orange figure (J) is the translated image of the yellow figure (M). ![]() The yellow figure (M) has been translated a distance of 9.00 cm to the right. The translated figure is called the image of the original figure. TranslationĪ figure undergoes a translation when it slides a certain distance in a certain direction. ![]() Let’s investigate three types of transformations: translations, reflections, and rotations. In the previous lesson we reviewed a few properties of polygons.In this lesson, we’ll explore transformations, which are changes to the size, shape, location, or orientation of a figure. ⬅ Previous Lesson Workshop Index Next Lesson ➡
