A scalene triangle
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
An Isosceles Triangle
If you meen the three angles, all tirangles angles add to 180 degrees. But all of the angles must be different, that's what makes it an acute triange. So three.
Yes.
A scalene triangle
Every triangle has at least three angles.
In plane geometry at least two angles must be acute in a triangle.
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
An Isosceles Triangle
Every triangle must have either 2 or else 3 acute angles. The least possible is 2.
