Measuring angles with a protractor can be tricky sometimes. Here are some common mistakes to watch out for:
Incorrect Alignment:
Make sure the center of the protractor is exactly on the tip of the angle (called the vertex). If it’s not lined up right, your measurement will be wrong!
Reading the Wrong Scale:
Protractors usually have two scales: one on the inside and one on the outside. Check which one matches with your angle.
Parallax Error:
Always look straight at the protractor when reading your angle. If you look from the side, you might read it wrong!
Not Checking the Angle Type:
Remember, angles come in different types:
If you can avoid these mistakes, you’ll measure angles like a pro!
