An obtuse angle = an angle greater than 90 degrees.
2 x (more than 90 degrees) = (more than 180 degrees).
But the sum of all 3 interior angles of any triangle is always exactly 180 degrees.
So: No triangle can have two obtuse angles.

Can an obtuse triangle have congruent angles?
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
Can an obtuse triangle have congruent sides?
Yes if it is in the form of an isosceles triangle with the other 2 acute angles being equal
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 are the angles in an obtuse triangle?
An obtuse triangle has 1 obtuse angle and 2 acute angles
What is a characteristic of a triangle right triangle and obtuse triangle?
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
Can an obtuse triangle have congruent angles?
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
Classification of triangle?
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
What triangle has 2 obtuse angles?
No triangle has 2 obtuse angles
What are the names of the triangles and how can you tell?
right triangle forms a 90 degree angle scalene triangle has no congruent sides isosceles triangle has at least 2 congruent sides equilateral triangle has 3 congruent sides acute triangle all angles measure less than 90 degrees and the obtuse triangle contains 1 obtuse angles.
Can an obtuse triangle have congruent sides?
Yes if it is in the form of an isosceles triangle with the other 2 acute angles being equal
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 are the angles in an obtuse triangle?
An obtuse triangle has 1 obtuse angle and 2 acute angles
What is an isosceles obtuse triangle?
An isosceles obtuse triangle is a triangle with 1 obtuse angle and only 2 congruent sides.
Is the isosceles triangle the only triangle with congruent sides and angles?
In an isosceles triangle 2 sides are congruent and 2 angles are congruent. In an equilateral triangle all 3 sides are congruent and all 3 angles are congruent also.
Can a scalene triangle have two congruent angles?
no because if an scalene triangle had 2 congruent angles it wouldn't be a scalene it would be a isosceles triangle because an isosceles triangle is the only triangle with 2 congruent angles
What is a characteristic of a triangle right triangle and obtuse triangle?
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
Can a scalene triangle have 2 congruent angles?
Not normally because it would be an isosceles triangle that has 2 congruent angles
