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.
What else can I help you with?
Triangle with no equal sides angles or sides?
A triangle with no equal sides or angles will always be classified as 'scalene'.
What angles do a scalene triangle have?
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
Are two angles of a scalene triangle congruent sometimes never or always?
A scalene triangle is a triangle in which all three sides and all three angles are different. Therefore two angles of a scalene triangle are NEVER congruent.
Which type of triangle always has all its sides and angles unequal?
scalene triangle
Does a scalene triangle have congruent angles?
No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.
Triangle with no equal sides angles or sides?

Are two angles of a scalene triangle congruent sometimes never or always?
A scalene triangle is a triangle in which all three sides and all three angles are different. Therefore two angles of a scalene triangle are NEVER congruent.
Does a scalene triangle always has three acute angles?
No, not always
Which type of triangle always has all its sides and angles unequal?
scalene triangle
Does a scalene triangle always have angles of unequal measures?
YES.
Is a scalene triangle always an obtuse triangle.?
A scalene triangle can have an obtuse angle and two different acute angles or three different acute angles but all angles in a triangle must add up to 180 degrees.
What are the exterior angles on a triangle?
The 3 exterior angles of any triangle add up to 360 degrees
What is the sum of exterior angles in a triangle?
The exterior sum of the angles of any polygon including a triangle is always 360 degrees.
Does a scalene triangle have congruent angles?
No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.
What is a triangle with no equal sides and no equal angles?
A triangle with no equal sides and no equal angles is called a scalene triangle. In contrast, a triangle with equal sides and equal angles is called an equilateral triangle. A triangle with two equal sides and two equal angles is an isosceles triangle.
A scalene triangle has 2 scalene angles also?
does a equilateral triangle have 2 interior angles
