Yes
Total of angles add up to 180, and all angles are below 90 degrees
Yes it can.
A scalene triangle is one where each side is a different length. Acute means that the largest interior angle of the triancle is less than 90 degrees A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted Triangle (Trigon) ABC. Scalene triangle is a triangle in which all the sides of the triangle will be unequal. The angles of triangle will be unequal. In the above triangle, the sides of the triangle are 8 cm, 10 cm, and 16 cm. The Scalene Triangle has no congruent sides. The Acute Triangle has three acute angles (an acute angle measures less than 90°) Scalene triangles are unusual in that the are defined by what they are not. Most triangles drawn at random would be scalene. The interior angles of a scalene triangle are always all different. The converse of this is also true - If all three angles are different, then the triangle is scalene, and all the sides are different lengths.
No, not in plane (Euclidean) geometry.
The Sum of the angles of a triangle drawn on a plain surface. is 180 degrees. However, the sum of the angles of a triangle drawn on a curved surface, such as a sphere ( the Earth) can be greater than 180 degrees.
3 and they add up to 360 degrees
yes of course

The word 'Triangle' is a collective noun for different shaped triangles. They are ;- Equilateral(Acute) ; all sides are the same length , and all angles are 60 degrees. Isosceles (Can be Obtuse) ; two sides are the same length and two angles are equal. Right-angles (only Acute) ; one of the angles is a right angle(90 degrees) Scalene ; All sides are different length and all angles are different values. May be either acute of obtuse. For ALL triangles, on a plane surface, the sum of the interior angles is ALWAYS 180 degrees. NB For triangles drawn on a 3-dimensional surface, ( a sphere ; the Earth) the angles may add to 360 degrees.

The Sum of the angles of a triangle drawn on a plain surface. is 180 degrees. However, the sum of the angles of a triangle drawn on a curved surface, such as a sphere ( the Earth) can be greater than 180 degrees.
All triangles have 3 interior angles that add up to 180 degrees
3 and they add up to 360 degrees
With 4 angles it will be a quadrilateral. Depending upon which angles are acute and which are obtuse and their sizes, and the side lengths it could be:a general quadrilaterala parallelograma rhombusa trapeziuma kite
