There must be 2 of them.
-- The 3 angles inside a triangle always add up to 180 degrees.
-- An obtuse triangle has one angle that's greater than 90 degrees.
-- That leaves less than 90 degrees total for the other 2 angles.
-- So they must be less than 90 degrees apiece.
-- In other words, "acute angles".
3. Any triangle, whether it's obtuse or acute will always have 3 angles. Pink23
It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).
It has 1 obtuse angle and 2 acute angles and the 3 interior angles add up to 180 degrees
It can have 0 or 2 right angles, 1 or 2 acute or obtuse angles.
none, equilateral triangles have three identical angles - all acute.None, an equilateral triangle as 3 angles of 60 degrees, which are all acute.
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
One and the two others are acute angles

First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.
It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).
Just the one and the other two angles must be acute.
Every triangle must have at least 2 acute angles, otherwise it is impossible to make the 3 sides connect.
It has 1 obtuse angle and 2 acute angles and the 3 interior angles add up to 180 degrees
There is one obtuse angle, and the other two are acute angle because in all the whole triangle is 180 degrees.
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).
It can have 0 or 2 right angles, 1 or 2 acute or obtuse angles.
