对象和像相似的变换为: - 位似Enlargement,我们需要知道位似中心centre of enlargement, 位似比scale factor(SF),即位似中心到像的距离与位似中心到对象的距离之比)。 另外,连续两个或多个变换依次进行,则可以看作一个变换,称为这几个变换的合成变换Combined transformations。 圆和尺规作图circles and constructions...
How to do scale factor enlargements What Is a Scale Factor? When enlarging a shape or image, we use a scale factor to tell us how many times bigger we want each line/side to become. For example, if we enlarged a rectangle by scale factor 2, as in the image above, each side would...

The scale factor is a measure by which the size of any geometrical figure could be varied with respect to original shape. Learn in detail scaling of the triangle and other shapes with examples.
Example 1. Find the scale factor when a square of side 4 cm is enlarged to make a square of side 8 cm.Solution: The formula for scale factor is:Scale Factor = Dimensions of New Shape/Dimension of Original ShapeTherefore, the scale factor for the given enlargement isScale Factor =8/4...
