![]() ![]() ROTATION If a shape spins 360, how far does it spin? 360 All the way around This is called one full turn. This is another way rotation looks center of rotation A ROTATION MEANS TO TURN A FIGURE ROTATION The triangle was rotated around the point. ROTATION What does a rotation look like? center of rotation A ROTATION MEANS TO TURN A FIGURE The center of rotation can be on or outside the shape. The point a figure turns around is called the center of rotation. ![]() Basically, rotation means to spin a shape. ROTATION A rotation is a transformation that turns a figure about (around) a point or a line. A B Arrow A is slide down and to the right. TRANSLATION In the example below arrow A is translated to become arrow B. A B Triangle A is slide directly to the right. TRANSLATION In the example below triangle A is translated to become triangle B. TRANSLATION What does a translation look like? original image x y Translate from x to y A TRANSLATION IS A CHANGE IN LOCATION. A translation is usually specified by a direction and a distance. An easy way to remember what translation means is to remember… A TRANSLATION IS A CHANGE IN LOCATION. TRANSLATION Basically, translation means that a figure has moved. With translation all points of a figure move the same distance and the same direction. TRANSLATION A translation is a transformation that slides a figure across a plane or through space. Examples of this type of transformation are: translations, rotations, and reflections In other transformations, such as dilations, the size of the figure will change. In some transformations, the figure retains its size and only its position is changed. In geometry, a transformation is a way to change the position of a figure. Translations, Rotations, and Reflections Demonstrate understanding of translations, rotations, reflections, and relate symmetry to appropriate transformations. Repeat a reflection for a second new parallelogram.- E N D - Presentation Transcript Translate your parallelogram according to the direction of translation, then record the reflected coordinates. Fill in the columns for Original Coordinates. Make a copy of the table and paste it into your notes. Reset the sketch and place a new parallelogram on the coordinate grid. Use the interactive sketch to complete the following table. Use the box containing the translate button to indicate the direction of the translation. Use the buttons labeled “New Square,” “New Parallelogram,” and “New Triangle” to generate a new polygon on the coordinate plane. In this section of the resource, you will investigate translations that are performed on the coordinate plane.Ĭlick on the interactive sketch below to perform coordinate translations. Translations do not change the size, shape, or orientation of a figure they only change the location of a figure. A translation is a transformation in which a polygon, or other object, is moved along a straight-line path across a coordinate or non-coordinate plane. What types of scale factor will generate an enlargement?Īnother type of congruence transformation is a translation.What types of scale factor will generate a reduction?.Choose resize points (center of dilation) of the origin, (0, 0), as well as other points in the coordinate plane.Ĭlick to see additional instructions in using the interactive sketch. Choose relative sizes (scale factors) less than 1 as well as greater than 1. Perform dilations with a triangle, a rectangle, and a hexagon. Once you have done so, use your experiences to answer the questions that follow. Second, you need a center of dilation, or reference point from which the dilation is generated.Ĭlick on the sketch below to access the interactive and investigate coordinate dilations. First, you need to know the scale factor, or magnitude of the enlargement or reduction. To perform a dilation on a coordinate plane, you need to know two pieces of information. A dilation can be either an enlargement, which results in an image that is larger than the original figure, or a reduction, which results in an image that is smaller than the original figure. Dilations can be performed on a coordinate plane. ![]()
