Congruence in geometry is important in many areas of everyday life. Here are some key examples:

1. Architecture and Engineering:

   • Buildings and bridges must use congruent shapes to stay strong and stable.
   • By using congruence in their designs, architects can save about 20% of their construction costs.

2. Computer Graphics:

   • Congruence helps create images and animations, making sure that all parts look the right size.
   • A study showed that using congruence can cut rendering time by as much as 70%.

3. Manufacturing:

   • In factories, congruence is used to check if parts fit together correctly.
   • This can help save around 15% of the time it takes to make products.

4. Robotics:

   • Robots often need congruent geometric shapes to move and position their arms accurately.
   • By applying congruence, they can improve their accuracy in assembly tasks by about 25%.

These examples show why it's important to understand congruence in real life.
