Not every triangle has to have an obtuse angle.
180 degrees. sum of every angle of triangle is always 180..no matter what type of triangle it is.
Angle a plus angle b subtract from 180 equals angle c
Yes, the measure of an exterior angle of a triangle can be greater than every interior angle of the triangle. An exterior angle is formed by extending one side of the triangle, and its measure is equal to the sum of the two non-adjacent interior angles. Since the sum of the interior angles of a triangle is always 180 degrees, an exterior angle can exceed individual interior angles, especially in cases where the triangle has one or more small angles.
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior angle.

A triangle is not an angle. In fact, every triangle is composed of three angles. One of them but not more may be a right angle, or one of them but not more may be an obtuse angle, but one or more of them must always be acute.
Angle a plus angle b subtract from 180 equals angle c
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.

no
-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .
The 3 interior angles of any triangle always add up to 180 degrees.
No.
Yes. Every triangle with an obtuse angle must have two acute angles.
