Drawing And Measuring Angles Maths Worksheet And Answers 9 | Free ... - Free Printable

The provided image is an "Angles Worksheet" that involves identifying and drawing angles. Below, I will explain how to approach each section of the worksheet:

---

Section A: Identifying Angles

This section contains diagrams of various angles, and the task is to classify them based on their type (acute, obtuse, right, straight, reflex).

#### Definitions:
1. Acute Angle: An angle less than 90°.
2. Right Angle: An angle exactly 90°.
3. Obtuse Angle: An angle greater than 90° but less than 180°.
4. Straight Angle: An angle exactly 180°.
5. Reflex Angle: An angle greater than 180° but less than 360°.

#### Analysis of Each Diagram:
1. Diagram 1: Acute angle (less than 90°).
2. Diagram 2: Obtuse angle (greater than 90° but less than 180°).
3. Diagram 3: Right angle (exactly 90°).
4. Diagram 4: Acute angle (less than 90°).
5. Diagram 5: Straight angle (exactly 180°).
6. Diagram 6: Reflex angle (greater than 180° but less than 360°).
7. Diagram 7: Reflex angle (greater than 180° but less than 360°).

Section B: Identifying Angles

Similar to Section A, this section also involves classifying angles based on their type.

#### Analysis of Each Diagram:
1. Diagram 1: Acute angle (less than 90°).
2. Diagram 2: Acute angle (less than 90°).
3. Diagram 3: Obtuse angle (greater than 90° but less than 180°).
4. Diagram 4: Right angle (exactly 90°).
5. Diagram 5: Reflex angle (greater than 180° but less than 360°).
6. Diagram 6: Straight angle (exactly 180°).
7. Diagram 7: Reflex angle (greater than 180° but less than 360°).

Section C: Identifying Angles

This section continues with the same task of classifying angles.

#### Analysis of Each Diagram:
1. Diagram 1: Acute angle (less than 90°).
2. Diagram 2: Acute angle (less than 90°).
3. Diagram 3: Obtuse angle (greater than 90° but less than 180°).
4. Diagram 4: Acute angle (less than 90°).
5. Diagram 5: Acute angle (less than 90°).
6. Diagram 6: Reflex angle (greater than 180° but less than 360°).
7. Diagram 7: Obtuse angle (greater than 90° but less than 180°).
8. Diagram 8: Reflex angle (greater than 180° but less than 360°).

Section D: Drawing Angles

In this section, you are tasked with drawing specific angles using a protractor.

#### Steps to Draw an Angle:
1. Place the center of the protractor at the vertex of the angle.
2. Align one arm of the angle with the baseline of the protractor.
3. Locate the given angle measurement on the protractor scale.
4. Mark the point corresponding to the angle measurement.
5. Draw a line from the vertex through the marked point to complete the angle.

#### Angles to Draw:
1. 15°
2. 34°
3. 67°
4. 95°
5. 145°
6. 171°
7. 200°
8. 280°
9. 300°
10. 196°
11. 283°
12. 317°

For each angle:
- Use the protractor to measure the exact degree.
- Ensure the angle is drawn accurately by aligning the protractor correctly.
