Dilation is a process of changing the size of an object or shape by decreasing or increasing its dimensions by some scaling factors. For example, a circle with radius 10 unit is reduced to a circle of radius 5 unit. The application of this method is used in photography, arts and crafts, to create logos, etc.
Dilations in the Coordinate Plane. Words To dilate a fi gure with respect to the origin, multiply the coordinates of each vertex by the scale factor k. Algebra (x, y) (kx, ky) When k > 1, the dilation is an enlargement. When k > 0 and k < 1, the dilation is a reduction.
Target 1 – Use proportions to identify lengths of corresponding parts in similar figures. Target 2 – Perform and identify dilations. Target 3 – Use ratios of lengths, perimeter, & area to determine unknown corresponding parts.
Dilations (B) Label the center of dilation. Dilations Answer (B)
Dilation is the process of resizing an object by a certain scale factor. In geometry shapes can be dilated by a scale up or a scale down factor. Learn what is dilation in geometry, definition, how to calculate scale factor and some solved examples.
