We recall that for equilateral triangles, all sides have equal length. This implies that the side lengths for both triangles are given as: AB=AC=BC=1 XY=XZ=YZ=10 Now, if we take the ratio between corresponding sides of both triangles, we observe that they have the same value: ...

If the sides of two triangles can be paired with the same ratio, we say that such triangles are similar. This property can be written as follows: aa′=bb′=cc′=sa′a=b′b=c′c=s where: a, b, c - sides lengths of the first triangle, a', b', c' - sides lengths of the...
Two right triangles are similar if: They both have the same set of 3 angles; and Their sides are proportional. The ratio of the lengths of corresponding sides of these triangles is called the scale factor. How do I use the similar right triangles calculator? To use this tool for finding ...
