Step 2: Measuring with

a Protractor 1

Introduction

Which three rules are important to remember when

measuring angles using a protractor?

Make sure the vertex of the angle you’re measuring is aligned with the centre of the cross on the base of the protractor.

Hold the protractor in your right hand when measuring.

Line up one side of the angle with the 0 line on the protractor.

Follow the other side of the angle up to the measurements on the protractor’s arc.

Always use the numbers on the outside of the protractor.

Can you think of any other rules?

Explain any errors.

Hannah

The angle is 45o

The angle is 135o

Chloe

Reasoning 1

Who has measured the angle correctly?

Explain any errors.

Chloe is correct because she has read the inner scale as the baseline is at 0 on the inner scale.

Hannah is incorrect because she has read the angle from 0 on the outside scale.

Hannah

The angle is 45o

The angle is 135o

Problem Solving 1

The children are drawing angles which will still be acute when joined together.

Has Nadia succeeded?

Nadia has succeeded because she estimated that the two angles would be 30o and 45o so would create a 75o angle and still be acute.
