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.
Do all triangles have two acute angles?
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
Can scalene triangles be acute or obtuse?
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
How are acute and obtuse triangles the same?
Similarities between these and all triangles are:They all have 3 sides and 3 angles. The sum of the three angles adds up to 180°.An acute angle is less than 90 degrees. An acute triangle has all three sides are acute.An obtuse angle is more than 90 degrees. An obtuse triangle has one angle which is obtuse, and because of the 180° rule above, the other two angles will be acute.So all triangles will have at least two acute angles.
What are triangles according to angle?
All triangles have 3 interior angles that add up to 180 degrees and they are:- Right angle triangle: 90 degree angle and 2 acute angles Obtuse triangle: An obtuse angle and 2 acute angles Scalene triangle: 3 acute angles of different sizes Isosceles triangle: 2 equal angles and another angle Equilateral triangle: 3 equal angles that each measures 60 degrees
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.
Do triangles have at least one right angle?
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
Do all triangles have two acute angles?

Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
What type of angle does a triangle have?
A triangle has at two acute angles and the third angle is either an acute angle, a right angle or an obtuse angle.
Which triangle has two acute angles and one obtuse angle?
If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.
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.
Can scalene triangles be acute or obtuse?
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
What are the different kinds of angles and triangle according to size and its angles?
Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle
Do triangles have at least two obtuse angles?
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
How are acute and obtuse triangles the same?
Similarities between these and all triangles are:They all have 3 sides and 3 angles. The sum of the three angles adds up to 180°.An acute angle is less than 90 degrees. An acute triangle has all three sides are acute.An obtuse angle is more than 90 degrees. An obtuse triangle has one angle which is obtuse, and because of the 180° rule above, the other two angles will be acute.So all triangles will have at least two acute angles.
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.
Is obtuse triangles scalene?
Yes, normally it is but it can also be an isosceles triangle if it has an obtuse angle and 2 equal acute angles.
