A triangle is not an angle. A triangle is made of three angles.
-- All three of them can be acute, but they don't need to be.
-- One of them can be obtuse but doesn't need to be.
-- One of them can be a right angle but doesn't need to be.
-- If any angle in the triangle is right or obtuse, then the other two
need to be acute.

If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.

There are five different types of triangles named after their angles. Right triangle, Acute triangle, Isosceles Triangle ,equilateral triangle, and obtuse triangle. The Obtuse Triangle is the triangle with an obtuse angle.
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.
Can you have a triangle with 1 acute 1 right and 1 obtuse angle?
No it is impossible a triangle can have: 3 acute angles 1 right and 2 acute angles 1 obtuse and 2 acute angles
