Not always because one of the interior angles could be obtuse.

Are all scalene triangles also acute triangles?
yes all scalene triangles are actue. All the angles are 60 degrees. :)
Triangle with all acute angles called?
equilateral triangle, acute triangle, some isosceles and scalene triangles
Are scalene triangles all obtuse?
No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
How many acute angles are in an acute triangle?
In an acute triangle, all three angles are acute.
All angles in a scalene triangle are acute?
A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
Which shapes have acute angles?
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.
Are all scalene triangles acute triangles?
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
A triangle with all acute angles?
Scalene
How many do all triangles measure?
I'm pretty sure all triangles measure 180 degrees because they have three angles that are either acute, right, or obtuse angles and the triangle has to be either an equilateral, iscoceles, or scalene triangle.
What is the difference between scalene obtuse and acute triangles?
There are two questions that have been mixed up here. There are three "main" types of angle: Acute, Obtuse and Reflex. Acute angles are from 1 to 89 degrees, Obtuse angles from 91 to 179 and Reflex angles anything over 181 degrees. An angle of 90 degrees is a right angle, and an angle of 180 degrees is just a line. There are three types of triangle: Equilateral, Isosceles and Scalene. Equilateral triangles have all three sides the same length (and the angles are all 60 degrees), isosceles triangles have two equal-length sides of length and two equal angles, and scalene triangles have all three sides different lengths, and all three angles are different.
What is the least number of angles an acute triangle can have?
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
What types of triangles have at least two acute angles?
All triangles need at least two acute angles
