Sides aren't acute, angles are. A triangle with three acute angles would be called (appropriately enough) an acute triangle.
They both have 3 sides but an isosceles triangle has two equal sides whereas an acute triangle with different acute angles has no equal sides and is said to be a scalene triangle, or an acute triangle with three equal acute angles (of 60° each) and three equal sides is called an equilateral triangle.
An acute triangle may have three, two, or no congruent sides.
An equilateral triangle.
Any triangle that has three equals sides must have three acute angles and is equilateral.

A scalene triangle is a triangle that has three unequal sides.
The name of a triangle is dependent on the type of angles within it. If it has a right angle it is called a right triangle, if it has an obtuse angle it is an obtuse triangle, and if all three sides are acute it is an acute triangle.

right triangle , a obtuse triangle, and a acute triangle
An equilateral triangle
Acute scalene triangle: A triangle with three sides of different lengths and all three angles less than 90 degrees. Acute isosceles triangle: A triangle with at least two sides of equal length and all three angles less than 90 degrees. Acute equilateral triangle: A triangle with three equal sides and all three angles measuring less than 60 degrees.
