Yes. You can always draw a "diagonal" line between opposite corners of any four-sided
figure. Then, cutting along that line, you wind up with two triangles out of which the figure
could have been made.

Because all other polygons are made from triangles as for example an 8 sided octagon has 6 triangles within it or a 6 sided hexagon has 4 triangles within it.
All four-sided figures are quadrilaterals.
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.

Yes
yes
Because there are 540 interior degrees in a five sided figure and the total sum of three triangles is 540 degrees
Yes because 3*180 are the interior degrees of a pentagon.
Yes because there are 540 degrees in a pentagon and 180 degrees in a triangle so 540/180 = 3 triangles.
You can always find opposite corners that can be connected with a line which divides the quadrilateral into two trilaterals.

Yes. Take any quadrilateral, and connect 2 opposite corners with a line segment. Now you have 2 triangles.
All four-sided figures are quadrilaterals.
All six-sided two dimensional figures are hexagons.
