Final answer:
A triangle with all sides measuring 8cm each is an equilateral triangle, which makes it an acute triangle as well because all the angles are less than 90 degrees.
Step-by-step explanation:
To determine whether the triangle is acute, obtuse, right, isosceles, equilateral, or scalene when all sides measure 8cm each, we use the definitions of these types of triangles. A triangle with all three sides of equal length is an equilateral triangle.
An equilateral triangle also has all three interior angles measuring 60 degrees, which makes it an acute triangle as well because all the angles are less than 90 degrees. Therefore, such a triangle with sides measuring 8cm each is both equilateral and acute, but specifically, it is an equilateral triangle due to all sides being of equal length.
