Actually, you cannot conclude anything this way, at least not in regular geometry. For instance, in a "perfect triangle," all 3 angles are acute. In a right triangle, one is a right angle and the other two are acute. It is also possible to have an obtuse angle and two acute angles. The thing is, the 3 angles must add up to 180 degrees.

How many acute angles are there in a triangle?
There may be either 2 or 3.If there are only 2, the third angle is equal to or greater than 90 degrees.(the sum of the three angles must equal 180 degrees)If there are 3, the triangle is called an acute triangle.
If a triangle has one acute angle is the triangle necessarily acute?
No, an acute triangle must have all 3 angles under 90 degrees. A triangle can have an acute angle and still be a right triangle or an obtuse triangle.
Is a scalene triangle always an obtuse triangle.?
A scalene triangle can have an obtuse angle and two different acute angles or three different acute angles but all angles in a triangle must add up to 180 degrees.
How many acute angles in an equilateral triangle?
An equilateral triangle has all three angles equal and they must sum to 180 degrees. So 180 divided by 3 is 60 which is an acute angle. There are three acute angles in an equilateral triangle.
A triangle with two acute angles must be a right angle?
No. The three angles in a triangle, in plane Euclidean geometry, must add to 180 degrees. Acute angles are less than 90 degrees. Therefore you may have a triangle with three angles which are 60 degrees for instance.
