Yes it can
Two.
An obtuse triangle must have two acute angles and these can be congruent.
In any right triangle, the two angles at either end of the hypotenuse are both always acute angles. But I don't think that would be called an 'acute' triangle, because an acute triangle is one in which all three angles are acute ones.
A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
No triangle is never acute in the sense that every triangle has at least two acute angles.
yes an obtuse triangle has two acute angles
Two.
A right angled triangle can only have two acute angles.
Two. Two acute angles in a right triangle.
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
In plane geometry at least two angles must be acute in a triangle.
An obtuse triangle must have two acute angles and these can be congruent.

A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
Yes it can. A triangle must have at least two acute angles.
