Yes, triangles can be irregular...
you can't
SCALENE because the sides are irregular
Circles, some triangles, and irregular polygons
irregular polygons are just polygons that do not have equal angles and side so a scaling and isosceles triangles are 2 and trapezoid is another.
You make a hexagon.Ans 2.With careful design of the size, shape and placement of the 6 triangles, you can produce : -any triangle, acute obtuse or scaleneany quadrilateral, regular or irregulara regular hexagonan irregular hexagonan irregular octagonan irregular decagonan irregular dodecagona huge variety of non-polygonal shapes.

Regular polygons have all equal length sides and irregular polygons do not.
Two triangles can but its an irregular shape

Some can, but not all. For example, rhombi, rhomboids, oblongs, and isosceles triangles can tessellate; however, most irregular polygons cannot. * * * * * True, but an incomplete answer. All triangles and quadrilaterals, whether regular or irregular, will tessellate. No regular pentagon will tessellate but (as of 2016), there are 15 irregular pentagons which will tessellate. There are 3 convex hexagons, (regular and 2 irregular) which will tessellate. No polygon with 7 or more sides, even if it is regular, will tessellate.
Quadrilaterals and Triangles, if you're asking for polygon categories.
There is no standard formula. It is necessary to partition the irregular hexagon into more convenient shapes such as triangles and quadrilaterals, find their areas and sum the results.
You will either get two triangles, two rectangles, or two irregular quadrilaterals.
A triangle is only a regular triangle in the form of an equilateral triangle
