Worksheet: Measuring Angles
In this worksheet, we will practice identifying correct and incorrect uses of protractors for measuring angles.
Chloe uses a protractor to measure the angle , as shown in the diagram. She gets a value of . Which of the following statements explains why this answer is incorrect?
- AThe maximum resolution of the protractor is , so the angle should be measured as .
- BThe resolution of the protractor is , so the angle should be measured as .
- CThe center of the protractor was not placed at the vertex of the two lines that form the angle .
Which of the following shows the correct position in which a protractor must be placed in order to measure the angle ?
Which of the following items can be used to measure angles?
- AA protractor
- BA balance
- CA thermometer
- DA micrometer
- EA meter ruler
The diagram shows two straight lines that intersect to form an obtuse angle and a reflex angle between them. A protractor is positioned at the intersection between the two lines.
