How to Use Similar Triangles
Two triangles that are the same shape, but not necessarily the same size, are called similar triangles. Similar triangles have corresponding angles that have identical measures. They also have proportional sides. This means that the relationship between...
This is known as the AAA similarity theorem. Due to this theorem, several authors
simplify the definition of similar triangles to only require that the corresponding ...
Two triangles are Similar if the only difference is size (and possibly the need to
turn or flip one around). These triangles are all similar: (Equal angles have been
Definition and properties of similar triangles - testing for similarity.
Given two triangles with some of their angle measures, determine whether the
triangles are similar or not.
Similar Triangles. ... Objects, such as these two cats, that have the same shape,
but do not necessarily have the same size, are said to be "similar".
Sal explains what it means for triangles to be similar, and how this follows from
the definition of similarity.
Two triangles are similar if and only if the corresponding sides are in proportion
and the corresponding angles are congruent.
Triangles are similar if their corresponding (matching) angles are congruent (
equal in measure) and the ratio of their corresponding sides are in proportion.
