If you're searching for how to find the scale factor of a triangle, this scale factor calculator is for you.
With this calculator, you can find the scale factor of similar triangles in two ways:
- Checking similarity: This option checks whether two triangles are similar or not, and in case they are, the tool calculates the triangle scale factor. You have to fill in all of the options. You can select between three similarity criteria related to the information known:
- Side-Side-Side (SSS);
- Side-Angle-Side (SAS); and
- Angle-Side-Angle (ASA);
- Finding the missing side: If you input the information about the first triangle and one of the sides of the second triangle, the tool will calculate the triangle scale factor and, as a bonus, the remaining dimensions of the second triangle.
How to find the scale factor of a triangle
To know how to find the scale factor of a triangle, first, we must understand what similar triangles are. Two triangles are similar if one of these conditions holds:
- Their corresponding sides are in proportion, so one triangle is a scaled version of the other. The scale factor measures the degree to which this occurs.
- Two corresponding angles are congruent.
🙋 If one of the above conditions is true, the other one will also be true.
Consider the following two triangles:
As the corresponding sides are in proportion, then:
Therefore, we can say , where the symbol indicates that the triangles are similar.
The term refers to the scale factor. It measures the proportion of similarity between two corresponding sides.

FAQs
How do I find the scale factor of two triangles?
To find the scale factor of two triangles, follow these steps: Check that both triangles are similar. If they are similar, identify the corresponding sides of the triangles. Take any known side of the scaled triangle, and divide it by its corresponding (and known) side of the second triangle. The result is the division equals the scale factor.
What is the leg length of a triangle RST dilated by a scale factor of 1/2?
If an isosceles triangle RST was dilated by a scale factor of 1/2, and the legs of the dilated triangle (R'S' and R'T') measured 8 units, the length of the legs of the original triangle must be 16 units.
