irregular triangle
No because an equilateral triangle is a regular polygon whereas an obtuse triangle is irregular
For example, you can divide the polygon into triangles, and calculate the area of each triangle.
Any polygon can have at least one right angled - for example a right angled triangle. An example of an irregular polygon with only right angles is a rectangle.

irregular triangle
No.
It is irregular as not all the sides have the same length.
A triangle is a polygon. It can be regular or irregular. If it's regular, then all three sides are the same length, and it's called an "equilateral triangle". If all three sides aren't the same length, then it's an irregular polygon.
Yes
Any triangle other than an equilateral triangle.
It is an irregular polygon such as a scalene triangle
It cannot be any regular polygon, not a rectangle. But it could be a triangle or irregular polygons with 4 or more sides.It cannot be any regular polygon, not a rectangle.

yes it is but it might look different and so it is an irregular triangle.
