Any shape with 4 acute angles must have more than 4 sides.
Any shape with more than 4 sides can have 4 acute angles (but doesn't have to).
A rhombus is a shape having two acute angles and four equal sides.
The shape you are describing is a rhombus. A rhombus has four equal sides (equilateral) and can have four acute angles if it is a special type called an acute rhombus. All rhombuses are quadrilaterals, as they have four sides.
it is a rhombus
No shape does. If a shape has four angles, the sum of the four angles is 360°. If two are right angles, their sum is 2 x 90° = 180°, leaving 360° - 180° = 180° for the two remaining angles. An acute angle is less than 90°, so the sum of two acute angles is less than 90° + 90° = 180°, but in this shape their sum must be equal to 180°; thus no shape can exist. If one angle is acute and the other is obtuse, then their sum can be 180° and the shape is a trapezium.

A shape that can contain no acute angles is a rectangle. In a rectangle, all interior angles are right angles, which are exactly 90 degrees. This means there are no angles smaller than 90 degrees, which are considered acute angles. Therefore, a rectangle is an example of a shape that contains no acute angles.

If the shape has 3 angles in all, where two of the angles are acute, then the shape is a scalene triangle.
If the figure has only four sides all together, then it's not possible for all four angles to be acute.
a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.
The only polygon with just acute angles is an acute angled triangle.
A diamond shape, which is a type of rhombus, has four angles. In a standard diamond, two of these angles are acute (less than 90 degrees) and the other two are obtuse (greater than 90 degrees). Therefore, a diamond has two acute angles.
you could count the sides or acute, obtuse, or right angles.
