Let's analyze and classify each shape step-by-step.
### Shape A
Given:
- Length of sides: 6 equal sides, each 1 cm
- Classify angles: 6 obtuse angles
- Regular/Irregular: Regular
- Name of shape: Regular hexagon
The shape has been correctly classified as a "Regular hexagon" since it has 6 equal sides and the angles are obtuse (more than 90 degrees but less than 180 degrees).
### Shape B
Given:
- Length of sides: 4 equal sides, each 1 cm
- Classify angles: 4 right angles
- Regular/Irregular: Regular
- Name of shape:
By definition, a shape with 4 equal sides and 4 right angles is a "Square". Therefore:
- Name of shape: Square
### Shape C
Given:
- Length of sides: 3 equal sides, length not provided
- Classify angles: Not provided
- Regular/Irregular: Irregular
- Name of shape: Irregular
A shape with 3 sides is a triangle. Since it is mentioned that it is irregular and lacks further classification of angles:
- Name of shape: Irregular Triangle
### Shape D
Given:
- Length of sides: 2 equal sides, each 4 cm
- Classify angles: 2 acute angles
- Regular/Irregular: Irregular
- Name of shape:
A quadrilateral with sides not all equal and some acute angles can be classified as an "Irregular Quadrilateral". Therefore:
- Name of shape: Irregular Quadrilateral
