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.

Every triangle must has ATLEAST two obtuse angles and one acute angle. OR all 3 as Obtuse.

Are the exterior angles of a scalene triangle always obtuse?
No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.
When is the circumcenter of a triangle in the exterior of the triangle?
All triangles with an obtuse angle will have the circumcentre outside the boundary of the triangle.
What types of triangles can have an obtuse angle?
An obtuse triangle
Is it possible to divide the square into 2 obtuse trangle?
No but it is possible to divide the square into 2 right angle triangles
Does every triangle have to have an obtuse angle?
no Not every triangle has to have one. Some triangles may be acute, meaning that none of their angles are over 90. Some triangles may be right, meaning that there is one right angle. Although some triangles may be obtuse, not all triangles are obtuse.

What triangle has at least one obtuse angle?
-- 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 . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.
What types of triangles can have an obtuse angle?
An obtuse triangle
How many obtuse angles does a obtuse triangle have?
Triangles do not have to have any obtuse angles but they can have one.
Is it possible to divide the square into 2 obtuse trangle?
No but it is possible to divide the square into 2 right angle triangles
Is there such thing as a right obtuse angle?
No. Right triangles are triangles with one angle exactly 90°, and obtuse angles are triangles with exactly one angle that is greater than, but not equal to, 90°.
Does an acute triangle have obtuse angles?
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
Which shapes have an obtuse angle?
Obtuse triangles have an obtuse angle, and regular shapes with a number of sides equal to or greater than five have angles that are all obtuse.
Does every triangle have to have an obtuse angle?
no Not every triangle has to have one. Some triangles may be acute, meaning that none of their angles are over 90. Some triangles may be right, meaning that there is one right angle. Although some triangles may be obtuse, not all triangles are obtuse.
What is three types of triangles?
They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles
Is an exterior angle of a triangle always acute?
No :) Because one angle of the triangle is always acute and so the exterior has to be obtuse.
