When using the converse of the Pythagorean Theorem, students often make some common mistakes. Let’s make things clearer with these important tips:

1. Confusing Triangle Types: Sometimes, students forget that the converse only works for right triangles. Always make sure to check the angles!

2. Wrong Side Length Calculations: It's super important to measure the sides correctly. Remember, if $c$ is the longest side, check that $a^2 + b^2 = c^2$ is true!

3. Mixing Up Side Orders: Some people get confused about which sides to square first. The formula is simple: $a^2 + b^2 = c^2$!

By avoiding these mistakes, you’ll get a good handle on the converse of the Pythagorean Theorem and do well on your geometry problems. Keep up the great work!
