A triangle is the only shape that can have only acute angles inside it.
Acute angles
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.

Acute angles
Just about any shape that isn't a circle can have two or more acute angles. But with some of them, you need to make them have acute angles.
There are many possible shapes with two acute angles.
A polygon, that is, a plane area bounded by any number (>2) of straight lines can have acute angles.
Any irregular polygon can have an acute angle. A regular triangle (equilateral) has three acute angles. All other triangles must have at least two acute angles. A quadrilateral, other than a rectangle (or square), must have at least one.
It has 3 acute angles. You can do this by multiplying however many sides it has by 2. I think this works. Try it with different shapes! Hope this helps!
you could count the sides or acute, obtuse, or right angles.
An equilateral triangle.
