Not every triangle has to have an obtuse angle.
-- 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 .
Yes. Every triangle with an obtuse angle must have two acute angles.
An obtuse triangle has an obtuse angle.
A triangle with 1 obtuse angle is called an obtuse triangle.
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 containing an obtuse angle is an obtuse triangle.

Obtuse Triangle- An obtuse triangle has one angle that is bigger than 90 degrees (Obtuse angle). The following is an obtuse triangle. ! Hope it helped:')
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.
No it is impossible for a right triangle to have an obtuse angle therefore it will have one right angle and two acute angles.
