Today we will learn how to measure an angle using a protractor. The key is to align the centre of the protractor with the vertex of the angle and zero line of the protractor with one arm of the angle.
Sometimes the neither arm of the angle is horizontal and in such problems kids may need to move the paper or their sitting position to align with at least one arm of the angle. In the worksheets couple of the problems show the protractor aligned with the angle vertex and one arm, and we need to learn the same way to put our protractor above the given angle.
Below are the worksheets;
