I am a 2 dimensional shape that has 3 acute angles. All my sides are the same length. I have no parallel sides

A two dimensional shape would only have an area but no volume. This includes the basic shapes like circle, triangle and quadrilaterals. If it has 3 angles, then it would have 3 sides. This is definitely a triangle. When all sides of a triangle are equal, it is called an equilateral triangle.
