Thales (c. 600 B.C.) used the proportionality of sides of similar triangles to measure the heights of the pyramids in Egypt. His method was much like the one we used in Example \(\PageIndex{8}\) to measure the height of trees. Figure \(\PageIndex{7}\). Using similar triangles to measure the height of a pyramid.4. Calculate the proportion of the side lengths between the two triangles. To use the SAS theorem, the sides of the triangles must be proportional to each other. To calculate this, simply use the formula AB/DE = AC/DF. Example: AB/DE = AC/DF; 4/2 = 8/4; 2 = 2. The proportions of the two triangles are equal. 5.This (SSS) is one of the three ways to test that two triangles are similar . For a list see Similar Triangles. Try this Drag any orange dot at P,Q,R.
