#When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the **similar triangles**. In Figure 1 , Ξ ABCβΌ Ξ **DEF**. Figure 1 **Similar triangles** whose scale factor is 2 : 1. The ratios of corresponding sides are 6/3, 8/4, 10/5.

**2**) If the **scale factor** is **2**, draw a line from the centre of **enlargement**, through each vertex, which is twice as long as the length you measured. If the **scale factor** is 3, draw lines which are three times as long. If the **scale factor** is 1/**2**, draw lines which are 1/**2** as long, etc. The centre of **enlargement** is marked.

Above, how do you find the scale factor of a fraction?

The simplified ratio, or fraction, will give you your **scale factor**. If you are **scaling** down, your **scale factor** will be a proper fraction. If you are **scaling** up, it will be a whole number or improper fraction, which you can convert to a decimal.

Long story short, how do you find the scale factor of two rectangles?

Having said that, how do you find the scale factor of enlargement?

Linear **scale factor** The size of an **enlargement**/reduction is described by its **scale factor**. For example, a **scale factor** of 2 means that the new shape is twice the size of the original. A **scale factor** of 3 means that the new shape is three times the size of the original.

What is the scale factor in geometry?

β **Scale Factor**: The ratio of any two corresponding lengths in two similar. geometric figures.

more ... The ratio of the length in a drawing (or model) to the length on the real thing. Example: in the drawing anything with the size of "1" would have a size of "10" in the real world, so a measurement of 150mm on the drawing would be 1500mm on the real horse.

A **scale factor of 1:3** means that one triangle is 3 times bigger than the other, for example. So, if the small triangle has a perimeter of 27, the big triangle has a perimeter 3 times as big. Doing the math, 3β
27=81 - the big triangle's perimeter, then, is 81 units.

To convert a measurement to a larger measurement simply multiply the real measurement by the **scale** factor. For example, if the **scale** factor is 1:8 and the measured length is 4, multiply 4 Γ 8 = 32 to convert.

To **find** the **scale factor** of the **drawing** to the actual fence, first write a ratio that compares of the two quantities. Next, compare the quantities using the same units. Convert feet to inches by multiplying the ratio by the conversion rate of 1 ft = 12 in. Then, simplify the fraction.

A reduction (think shrinking) is a dilation that creates a smaller **image**, and an **enlargement** (think stretch) is a dilation that creates a larger **image**. If the **scale factor** is between 0 and 1 the **image** is a reduction. If the **scale factor** is greater than 1, the **image** is an **enlargement**.
