This geometry math tutorial from NutshellMath offers homework help with geometry and the concept of similar triangles. Proving similar triangles, and using properties of similar triangles to find unknown dimensions of geometric figures. Similar triangles are ones in which all three angles of one triangle are congruent to the corresponding angles of another triangle. The corresponding sides of similar triangles are not necessarily congruent.
In order to prove two triangles similar, it is necessary to prove all the angles congruent. Doing so may require using properties such as those governing parallel lines and transversals, or vertical angles. This tutorial offers an example of proving triangles similar.
The most important property of similar triangles is that the ratio of any two corresponding sides of two similar triangles is equal to the ratio of any other two corresponding sides. This property can be used to find unknown dimensions of similar triangles. To do so, set up a proportion between the ratios of two sets of corresponding sides, and have the unknown side be the only variable in the equation. Use cross-multiplication and algebra to solve for the unknown.
Similar triangles are a very important concept in geometry. Learning the properties of similar triangles will help in finding unknown quantities and other relationships in geometric figures.
