# CA5: Advanced Geometric Reasoning with AI

## 🎯 Project Overview

A comprehensive implementation of **Advanced Geometric Reasoning** systems that combine neural networks with symbolic reasoning to solve complex geometry problems. This project demonstrates state-of-the-art techniques in neurosymbolic AI, multimodal reasoning, automated theorem proving, and intelligent problem-solving for geometric challenges.

### 🌟 What is Geometric Reasoning?

Geometric reasoning is the process of understanding, analyzing, and solving problems involving shapes, spatial relationships, and mathematical properties. This project uses AI to:

- Parse natural language geometry problems
- Analyze geometric diagrams
- Apply relevant theorems automatically
- Generate step-by-step solutions
- Verify correctness of proofs

**Example:**

- **Problem**: "In a right triangle with sides a=3 and b=4, find the hypotenuse c"
- **AI Process**: Parse problem → Identify right triangle → Apply Pythagorean theorem → Calculate c=5 → Verify solution
- **Solution**: "c = 5 (using Pythagorean theorem: 3² + 4² = 5²)"

**Implementation**: `NeuralSymbolicGeometryReasoner` class

**Components**:

- **Feature Extraction Network**: Multi-layer perceptron for extracting features from geometric entities
- **Multi-Head Attention**: Models relationships between geometric elements
- **Relation Predictor**: Identifies geometric relationships (parallel, perpendicular, congruent, etc.)
- **Theorem Predictor**: Suggests applicable theorems based on problem structure
- **Symbolic Inference Engine**: Applies logical rules and geometric axioms

**Usage Example**:

```python
from src.hybrid.solver import NeuralSymbolicGeometryReasoner
# Initialize the reasoner
reasoner = NeuralSymbolicGeometryReasoner(
    input_dim=10,
    hidden_dim=128,
    num_relations=8,
    num_theorems=15
)
# Process geometric entities
geometric_entities = torch.randn(5, 10)  # 5 entities, 10 features each
results = reasoner(geometric_entities)
# Extract neural features and relations
features = results['features']
relations = results['relations']
theorems = results['theorems']
# Apply symbolic inference
symbolic_results = reasoner.symbolic_inference(features, relations)
print(f"Applied Theorems: {symbolic_results['applied_theorems']}")
print(f"Derived Facts: {symbolic_results['derived_facts']}")
```

**Benefits**:

    text_dim=768,
    visual_dim=2048,
    hidden_dim=512
)
# Process a geometric problem
text_description = """
In triangle ABC, point A is at (0,0), point B is at (3,0),
and point C is at (0,4). Find the area of the triangle.
"""
# Optional: Include diagram image
diagram_image = None  # or load image as numpy array

- **Relation Detection**: Finds relationships (parallel, perpendicular, tangent, congruent)
- **Constraint Extraction**: Extracts numerical constraints (coordinates, lengths, angles)
- **Goal Identification**: Determines what needs to be found or proven
- **Theorem Suggester**: Recommends applicable theorems based on problem structure

**Usage Example**:

```python
from src.hybrid.solver import FormalGeometryParser
# Initialize the parser
parser = FormalGeometryParser()
# Parse a geometric problem
problem_text = """
In triangle ABC, point A is at (0,0), point B is at (3,0),
and point C is at (0,4). Prove that angle ABC is a right angle.
"""
# Parse the problem
parsed = parser.parse_problem(problem_text)
# Extract formal representation
print(f"Entities: {parsed['entities']}")
print(f"Relations: {parsed['relations']}")
print(f"Constraints: {parsed['constraints']}")
print(f"Goal: {parsed['goal']}")
# Get theorem suggestions
theorems = parser.suggest_theorems(parsed)
print(f"Suggested Theorems: {theorems}")
```

**Formal Representation Example**:

```python
{
    'entities': {
        'points': ['A', 'B', 'C'],
        'triangles': ['ABC'],
        'lines': ['AB', 'BC', 'CA']
    },
    'relations': {
        'perpendicular': [('AB', 'AC')],
        'forms_triangle': [('A', 'B', 'C')]
    },
    'constraints': {
        'coordinates': {'A': (0, 0), 'B': (3, 0), 'C': (0, 4)}
    },
    'goal': {
        'type': 'prove',
