Do you have a pattern of eight triangles?

The pattern consisting of eight triangles is as follows. The figure composed of eight triangles varies according to the placement position of the eight triangles. For example, eight triangles can be used to make a trapezoid. Their spelling is: first, put five triangles into three triangles and two triangles into an inverted pendulum, thus forming a trapezoid, and then put a triangle with two triangles and an inverted pendulum on this trapezoid, thus forming a big trapezoid.

Eight triangles

For ordinary triangles, only parallelograms can be formed. Eight isosceles right triangles can form squares, rectangles, isosceles trapezoid parallelograms and diamonds. Eight congruent isosceles triangles can form a trapezoid or quadrilateral. Eight congruent equilateral triangles can form a square, a rectangle, an isosceles trapezoid and a parallelogram. Eight congruent right triangles can form a parallelogram and a diamond.
