you could count the sides or acute, obtuse, or right angles.
If it's a right angle triangle then you'll have difficulty in finding the obtuse angle because it will not have one.
By using trigonometry that is applicable to a right angle triangle.
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.
An acute triangle
You find the orthocenter by constructing the altitudes from the vertices in a triangle. If the triangle is obtuse, the orthocenter will fall outside the triangle. If the triangle is acute, the orthocenter will fall on the inside of the triangle. If the triangle is a right triangle, the orthocenter will lie on a vertix.

Well 90% is a complete right angle so... it is obtuse if it is over 90% and if it is below 90% it is an acute angle <3
If it's a right angle triangle then you'll have difficulty in finding the obtuse angle because it will not have one.

An acute triangle
When you have and obtuse triangle and you are trying to find the Orthocenter
if you know what a acute triangle looks like and you know what a isosceles triangle looks like just combined them together and then find the angles and degrees you'll find what a acute isosceles triangle looks like if you got the degrees right and angles
20, 70 and 90 degrees.
The answer depends on what information you do have about the triangle: the lengths of the other two sides, or the hypotenuse (longest side) and one of the acute angles, or the other leg and one of the acute angles, etc.
