similar triangles! Sam measures a stick and its shadow (in meters), and also the shadow of the tree, and this is what he gets: Now Sam makes a sketch of the triangles, and writes down the "Height to Length" ratio for both triangles: Height: Shadow Length: h 2.9 m = 2.4 m 1.3 ...

Since these triangles are similar, then the pairs of corresponding sides are proportional. That is,A : a = B : b = C : c. In words, this tri-part equation says, "Big-A is to little-A as big-B is to little-B and as big-C is to little-C". This proportionality of correspondin...
You can also use similar triangles to show that two lines are parallel. For example, suppose that ΔADE ~ ΔABC in Figure 14.5. You can prove that ¯DE ¯BC. Example 2: If ΔADE ~ ΔABC as shown in Figure 14.5, prove that ¯DE ¯BC. ...
These scholars have stated that the golden canon results in these properties, but none of them have shown why it does. Using basic geometry, and in particular similar triangles, this article addresses the question.Stanley M. MaxDepartment of Mathematics and Statistics...

Additional Properties of Proportions: 1.Reciprocal Property: If two ratios are equal, then their reciprocals are also equal. 2.If you interchange the means of a proportion, then you form another true proportion. 3.In a proportion, if you add the value of each ratio’s denominator to its nu...
