Two right triangles are similar if their hypotenuse and one other side have the same ratio of lengths. In this case, there are several equivalent conditions such as the right triangles having an acute angle of the same measure, or having the lengths of the sides being in the same proportion...
The SAS Similarity Theorem defines that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent then that two triangles will be termed as similar. SSS or Side-Side-Side Similarity If all the three sides of a triangle are e...

You're looking at a pair of triangles and a pair of rectangles that you've made. What are the criteria for checking to see if two figures are similar? There are two. The first is that the corresponding angles are all congruent to each other. Corresponding means they are located at ...
Sine, cosine, and the rest of the trig family work off angles. And angles are perfect for similarity since size doesn’t matter (how long do the sides of a 45 degree angle need to be? It doesn’t matter!). Because triangles with the same angles are similar, we can use the ratios ...
To clarify the concept of OPA we here provide a simple example. Consider the triangles A, B and C with the following configuration matrices: $$\begin{aligned} {\mathbf {A}}= \left[ \begin{array}{c@{\quad }c} 1 &{} 0 \\ 0 &{} 1 \\ -1 &{} 0 \\ \end{array} \right] ...
Chen [48] sought the topological relations between two polygons by decomposing a polygon into triangles. In this article, we do not distinguish the topological relations as Chen did, but rather, we take the polygon as a whole. The spatial topological relations are determined based on the ...
and if we define at the point 𝐯𝑖,vi, #𝑓#f—a number of adjacent triangular faces, and 𝜃𝑖𝑗θij—an angle of 𝑗jth adjacent triangle, and 𝒜𝐵AB—area of the first ring of triangles around the point 𝐯𝑖vi, we can find the Gaussian curvature and the mean curva...
Then, the possible values for A − and A + illustrated in Figure 1 as the two triangles. As the center of gravity, D − and D + are the most informative points in the triangle A − and A + , respectively. Figure 1. Possible value for A − and A + . However, < μ A...
