Not always because one of the interior angles could be obtuse.
yes all scalene triangles are actue. All the angles are 60 degrees. :)
equilateral triangle, acute triangle, some isosceles and scalene triangles
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.
In an acute triangle, all three angles 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.
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.
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.
Scalene
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
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.
No, but all equilateral triangles are acute. Acute: All angles of the triangle are less than 90 degrees. Equilateral: All angles of the triangle are 60 degrees.
All triangles need at least two acute angles
