Common Mistakes Students Make with Angle Relationships

When working with angles, students often make a few common mistakes. Here are some things to watch out for:

1. Confusing Angle Types: About 30% of students mix up complementary angles and supplementary angles.

   • Complementary angles add up to 90 degrees.
   • Supplementary angles add up to 180 degrees.

2. Overlooking Vertical Angles: Around 40% of students forget that vertical angles are always equal.

   • This can lead to wrong answers when figuring out angle sizes.

3. Not Using Theorems Properly: About 25% of students struggle to use theorems correctly.

   • This can cause mistakes when trying to find unknown angles.

4. Making Calculation Mistakes: Roughly 15% of students have trouble with basic math.

   • They might add or subtract angle measures incorrectly.

Being aware of these common mistakes can help students do better with angles!
