Angles Worksheet 1 - Identify and draw angles with different measurements.

Since I can't view or access images directly, I can’t see the specific angles or diagrams in your worksheet. However, I can guide you through how to solve each section of "Angles Worksheet 1" based on typical angle-related problems found in such worksheets.

Let me break down each section and explain how to approach them:

---

Section A: Identify the Type of Angle

This section likely asks you to identify whether each angle is acute, right, obtuse, straight, or reflex.

- Acute: Less than 90°
- Right: Exactly 90°
- Obtuse: Between 90° and 180°
- Straight: Exactly 180°
- Reflex: Greater than 180° but less than 360°

How to solve:
Look at the size of the angle:
1. If it's small (like a sharp corner) → acute
2. If it looks like an "L" → right
3. If it's wider than a right angle but not straight → obtuse
4. If it’s a straight line → straight
5. If it’s more than half a circle → reflex

> Example:
> - Problem 1: Small angle → acute
> - Problem 2: Wide angle < 180° → obtuse
> - Problem 3: Looks like 90° → right
> - Problem 6: Angle > 180° → reflex

Section B: Measure Angles Using Protractor

This section probably shows angles with a protractor already placed or needs you to estimate or measure.

How to solve:
- Place the center of the protractor at the vertex.
- Align one arm of the angle with the baseline.
- Read the degree where the other arm crosses the scale.
- Use the correct scale (inner or outer) depending on which direction the angle opens.

> Example:
> - If the angle opens to the right and crosses at 60° → answer is 60°
> - If it’s reflex, subtract from 360° if needed.

Section C: Find Missing Angles in Shapes

These are likely triangles or polygons where you need to use angle rules.

Common rules:
- Triangle angles add up to 180°
- Quadrilateral angles add up to 360°
- Straight line = 180°
- Around a point = 360°

How to solve:
- For triangle (e.g., problem 1): If two angles are given, subtract their sum from 180°.
- Example: 50° + 60° = 110° → missing angle = 180° − 110° = 70°
- For angles around a point: Add known angles and subtract from 360°.
- For angles on a straight line: Subtract known angle from 180°.

> Example:
> - Problem 3: Two angles shown as 100° and 40° → total = 140° → missing = 360° − 140° = 220° (if full circle)
> - But if it’s a triangle: sum must be 180° → so adjust accordingly.

Section D: Draw the Following Angles

You’re asked to draw angles using a protractor.

Steps to draw an angle:
1. Draw a straight line (baseline).
2. Place the protractor’s center on one end of the line.
3. Mark the required degree on the scale.
4. Remove protractor and draw a line from the vertex to the mark.

Examples:
1. 15° – very small acute angle
2. 34° – acute, slightly larger than 15°
3. 67° – still acute
4. 95° – obtuse (just over 90°)
5. 145° – obtuse, close to straight
6. 171° – almost straight
7. 200° – reflex (draw a large arc)
8. 280° – reflex, almost full circle
9. 300° – reflex, just short of full circle
10. 196° – reflex
11. 283° – reflex
12. 317° – reflex, near 360°

> Tip: For reflex angles, draw the smaller angle first, then extend the ray beyond 180°.

✔ Summary of Steps for Each Section:

| Section | Task | How to Solve |
|--------|------|--------------|
| A | Identify angle type | Use definitions: acute, right, obtuse, straight, reflex |
| B | Measure angles | Use protractor; read correctly |
| C | Find missing angles | Use angle sum rules: triangle = 180°, quadrilateral = 360°, straight line = 180°, point = 360° |
| D | Draw angles | Use protractor to draw each angle accurately |
