A square already has 2 right angle triangles within it
Four triangles, similar to the large one, but one third the size.
Two triangles are congruent if the six elements of one triangle (three sides and three angles) are equal to the six elements of the second triangle and the two triangles have a scale factor of 1. However, in four special cases it is only necessary to match three elements to prove that two triangles are congruent. The matching of four elements is sometimes necessary, and the matching of five elements would put the matter beyond any doubt.
If the 3 interior angles are the same then the triangles are similar
There are 3 triangles in a pentagon
Three triangles.
three triangles, and 1 square+2 triangles
square and 2 triangles put together
can two triangles put together make a square
parallelograms
a rectangle
They will form a 4 sided quadrilateral if the triangles are the same sizes.
The sacred crest is the image of three triangles put together to create one white triangle in the middle.
a square...

yes a square
Four triangles, similar to the large one, but one third the size.
