The orange and green quadrilaterals are congruent; the blue one is not congruent to them. Congruence between the orange and green ones is established in that side BC corresponds to (in this case of congruence, equals in length) JK, CD corresponds to KL, DA corresponds to LI, and AB corresponds to IJ, while angle ∠C corresponds to (equals) angle ∠K, ∠D corresponds to ∠L, ∠A ...
Construct the orthocenter of triangle and three midpoints (say A', B' C' ) between vertices and orthocenter. Construct a circumcircle of A'B'C' . This is the nine-point circle, it intersects each side of the original triangle at two points: the base of altitude and midpoint. Construct an intersection of one side with the circle at midpoint now ...

The two triangles on the left are congruent. The third is similar to them. The last triangle is neither congruent nor similar to any of the others. Congruence permits alteration of some properties, such as location and orientation, but leaves others unchanged, like distances and angles.

This includes a compressed triangle index array and compressed vertex arrays (one array for each vertex attribute). Due to the many steps of data processing that are required for implementing the compression, interacting with the file format directly is usually more complex than interacting with other, uncompressed triangle mesh file formats ...
Congruence [ edit ] If A , B are two points on a line a , and if A ′ is a point upon the same or another line a ′, then, upon a given side of A ′ on the straight line a ′, we can always find a point B ′ so that the segment AB is congruent to the segment A ′ B ′.
Let l, m, n be integers greater than or equal to 2. A triangle group Δ(l,m,n) is a group of motions of the Euclidean plane, the two-dimensional sphere, the real projective plane, or the hyperbolic plane generated by the reflections in the sides of a triangle with angles π/l, π/m and π/n (measured in radians).
