**Calculating**the Scaled Distance using the Actual Distance. If the

**scale**is 1 : x, then divide the actual distance by x to

**calculate**the map distance.

How do you figure out the scale factor of a dilation?

**Dilation scale factor**2: Starting with ΔABC, draw the

**dilation**image of the triangle with a center at the origin and a

**scale factor**of two. Notice that every coordinate of the original triangle has been multiplied by the

**scale factor**(x2).

**Dilation**with

**scale factor**2, multiply by 2.

What is the difference between the scale and the scale factor?

Two triangles are

**similar**if the lengths of the**corresponding**sides are**proportional**; that is, if a = kp, where k is a constant, then b = kq, and c = kr. In this case, the constant k is the “scale factor.” The scale factor describes the relationship between the two**similar**triangles.
