+# Congruence of Arcs - Manim Animation
+
+This project contains a comprehensive educational Manim animation explaining the concept of "Congruence of Arcs" in geometry. The animation is designed to be clear, engaging, and educational for students who find this topic challenging.
+
+## Features
+
+- **7 Well-Structured Scenes**: Each covering a specific aspect of arc congruence
+- **Slow-Paced Learning**: Designed for student comprehension with adequate wait times
+- **Visual Clarity**: Clean layouts, soft color contrasts, and clear annotations
+- **Interactive Elements**: Exercise scenes with step-by-step reveals
+- **Smooth Transitions**: Professional animations between concepts
+- **Modular Design**: Each scene can be run individually
+
+## Scene Breakdown
+
+### Scene 1: Introduction to Arcs
+- Introduces the basic concept of an arc
+- Shows a clean circle with marked endpoints
+- Defines what an arc represents geometrically
+
+### Scene 2: Defining Congruent Arcs
+- Displays two identical circles side-by-side
+- Shows congruent arcs with equal measurements
+- Introduces the formal definition of congruent arcs
+
+### Scene 3: Degrees and Length of Arcs
+- Demonstrates the relationship between central angles and arcs
+- Shows the arc length formula visually
+- Emphasizes the mathematical connection
+
+### Scene 4: Examples of Congruent and Non-congruent Arcs
+- Provides clear visual examples
+- Uses color coding for easy identification
+- Compares congruent vs. non-congruent arc pairs
+
+### Scene 5: Exercise – Identifying Congruent Arcs
+- Interactive learning with three practice problems
+- Shows hints (angle measurements) before revealing answers
+- Reinforces learning through active participation
+
+### Scene 6: Recap and Key Points
+- Summarizes all major concepts learned
+- Bullet-pointed key takeaways
+- Consolidates understanding
+
+### Scene 7: Closing Remarks
+- Final reinforcement of core concepts
+- Gentle conclusion with encouraging message

+
+## Design Philosophy
+
+### Educational Focus
+- **Slow Pacing**: Each concept is given adequate time for absorption
+- **Clear Annotations**: All text is large enough and well-positioned
+- **Visual Hierarchy**: Important elements are highlighted with appropriate colors
+- **Progressive Complexity**: Concepts build upon each other logically
+
+### Visual Design
+- **Soft Color Palette**: Easy on the eyes for extended viewing
+- **Consistent Styling**: Uniform font sizes and spacing throughout
+- **Clean Layouts**: Uncluttered scenes focus attention on key concepts
+- **Professional Appearance**: Suitable for classroom presentation
+
+### Technical Features
+- **Modular Architecture**: Each scene is self-contained
+- **Smooth Animations**: Professional transition effects
+- **Responsive Design**: Works well at different resolutions
+- **Error-Free Code**: Thoroughly tested animations
+
+## Color Scheme
+
+- **Blue (#3498db)**: Primary concept color, main title
+- **Green (#2ecc71)**: Scene titles, positive examples
+- **Red (#e74c3c)**: Negative examples, important points
+- **Yellow (#f1c40f)**: Measurements, formulas, highlights
+- **White (#ffffff)**: Standard text, circles
+- **Background**: Black for optimal contrast
+
+## Target Audience
+
+This animation is specifically designed for:
+- **Middle School Students** (Ages 11-14)
+- **High School Geometry Students** (Ages 14-18)
+- **Students struggling with arc concepts**
+- **Teachers looking for visual aids**
+- **Self-learners seeking clear explanations**
+
+## Educational Outcomes
+
+After viewing this animation, students will be able to:
+1. Define what an arc is in geometric terms
+2. Understand the concept of congruent arcs
+3. Recognize the relationship between central angles and arc congruence
+4. Calculate arc measurements using the arc length formula
+5. Identify congruent and non-congruent arcs in practice problems
+6. Apply their knowledge to solve geometry problems involving arcs
+
+## Prerequisites
+
+- Basic understanding of circles
+- Familiarity with angles and degrees
+- Elementary knowledge of geometry terminology
+
+## Technical Requirements
+
+- Python 3.7+
+- Manim Community Edition or ManimGL
+- All dependencies listed in requirements.txt
+
+## Customization
+
+The animation can be easily customized by modifying:
+- **Colors**: Change the color constants at the top of each scene
+- **Timing**: Adjust `self.wait()` durations for different pacing
