Understanding triangle congruence can seem tough for students, especially when trying to use it in real life.

Here are some reasons why it can be tricky:

1. Complex Shapes: Many design projects include complicated shapes, and triangles are often important in these designs.

2. Getting It Right: Using congruence rules like SSS (Side-Side-Side) or ASA (Angle-Side-Angle) can result in mistakes if they're not completely understood.

3. Pythagorean Theorem: Sometimes, people don’t use the formula $a^2 + b^2 = c^2$ correctly.

To make these challenges easier, you can:

• Practice regularly
• Solve problems that relate to real life
• Work together with classmates

Doing these things can help you understand triangle congruence better and use it in different situations.
