No because it can only contain a right angle and two acute angles
A scalene triangle CAN also be a right triangle. For a triangle to be scalene, all 3 sides must be of different lengths. If you draw a triangle with a 90 degree right angle (ie. a right triangle) you will see that it's very easy for the sides to be unequal lenghts.
2:.
absolutley not it is bigger than a right angle 90+
Equilateral Triangles do not contain right angles, since all angles in this shape are equal and it is impossible to make a triangle that consists of three 90 degress angles. Isosceles and Scalene may contain a right angle.
None
