Common Mistakes Students Should Avoid:

1. Mixing Up Ratios:

   • For a 45-45-90 triangle, the ratio is 1:1:√2.
   • For a 30-60-90 triangle, the ratio is 1:√3:2.

2. Getting Angles Wrong:

   • Mistakes can happen when you confuse the order of angles. This can lead to wrong side lengths.

3. Ignoring the Pythagorean Theorem:

   • Don't forget to check if a² + b² = c². Not doing this can give you the wrong measurements.

It's interesting to note that 54% of students have trouble with identifying side ratios correctly.
