WebA dilation is a transformation in which each point on a figure moves along a line and changes its distance from a fixed point. The fixed point is the center of the dilation. All of the original distances are multiplied by the same scale factor. For example, triangle is a dilation of triangle . The center of dilation is and the scale factor is 3. WebCreate a dilation of a polygon on a square grid given a scale factor and center of dilation. Identify the image of a figure on a coordinate grid given a scale factor and center of dilation.

WebPerform a dilation on the coordinate plane. The dilation should be centered at 9, negative 9, and have a scale factor of 3. So we get our dilation tool out. We'll center it-- actually, so it's already actually centered at 9, negative 9. We could put this wherever we want, but let's center it at 9, negative 9. http://mathletenation.com/content/dilations-coordinate-grids

When we divide the points, then we also divide the length. For example, let's say we have a square with side length 2 and vertices at (2, 2), (0, 2), (2, 0), and (0, 0). If we shrink this square by 2, we divide each point by 2. how did the filipinos fight the spaniards
