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.
