Angle Bisector

Every time you fold the paper, you’re bisecting the angle, which means you’re dividing the angle into
two equal parts. The line created by the fold is known as the angle bisector.

Mind the Mistake, Mend the Mistake!
When using a protractor, it’s easy to make errors. Here are some common mistakes and how to fix
them:

1. Incorrect Placement:

1. Mistake: Not placing the protractor's center on the vertex.

2. Fix: Ensure the center point of the protractor is exactly on the vertex.

2. Misalignment:

1. Mistake: The baseline of the angle isn’t aligned with the 0° line.

2. Fix: Align one arm of the angle with the 0° line on the protractor.
