Two scalene right triangles that are congruent, that is, that have identical size and shape, if joined together to form a quadrilateral, will form a rectangle.
Any 2 congruent triangles joined together will form a 4 sided quadrilateral
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
If they are congruent right angle triangles then just join them together side by side to form a parallelogram.
there are 14 obtuse angled triangles. to work this out, join all the vertices together, making a 7-pointed star. then count all the obtuse-angled triangles. i got 14...you might get a different answer, if so, i apologise. lol i know where u got this question from... anyway hoped i helped :)

You make a dimondxoxoxoxoxoxoxoxo

Divide each of the sides of the triangle into three. Join corresponding points on each pair of sides.
trapezoid
Join them together

Take any two points on its perimeter. Join them together and, if required, cut along that line. You now have non-regular quadrilateral that is divided.Take any two points on its perimeter.

There is more than one way to join two triangles. It would be possile to assemble a parallelogram out of two congruent equilateral triangles.
No, they do not.
just have 4 lines that join up... a quadrilateral is a 4 sided shape
