Step-by-step solution for: Working With Congruent Angles | 8th Grade Geometry Worksheets
Since I can't view or access images directly, I can't see the specific angles or diagrams in your uploaded image. However, based on the title and description you provided — "Working With Congruent Angles" — I can guide you through how to solve this type of problem and explain the concepts involved.

The worksheet has two parts:
#### Part 1: Draw the congruent angle for each angle below.
- You are given several angles (labeled A, B, C, etc.), and you need to draw an angle that is congruent to each one.
- Congruent angles are angles that have the same measure (same degree), regardless of orientation or size.
#### Part 2: Draw a congruent angle for each angle below.
- This time, you're given specific angle measures:
- A) 60°
- B) 120°
- C) 30°
- D) 200°
- You must draw an angle with the exact same measure as each.
---
#### 🔧 Tools Needed:
- Protractor (to measure and draw angles)
- Ruler or straightedge
- Pencil
---
#### For Part 1: Drawing Congruent Angles from Given Diagrams
1. Measure the given angle using a protractor:
- Place the center of the protractor at the vertex of the angle.
- Align the baseline with one side of the angle.
- Read the degree measure where the other side crosses the protractor scale.
2. Draw a new angle with the same measure:
- Draw a ray (a line with one endpoint).
- Place the protractor on the endpoint of the ray.
- Mark the same degree measure on the protractor.
- Draw a second ray from the endpoint through the mark.
- The new angle should look different in position or orientation but have the same measure.
> 🔁 Example: If the original angle is 45°, your drawing should also be 45° — even if it's pointing upward or downward.

#### For Part 2: Drawing Specific Angles
You’re given exact measurements, so:
1. A) 60°
- Draw a ray.
- Use the protractor to mark 60° from the ray.
- Draw another ray from the vertex through the 60° mark.
2. B) 120°
- Same process — draw a ray, then mark 120°.
3. C) 30°
- Measure and draw a 30° angle.
4. D) 200°
- This is a reflex angle (greater than 180°).
- Draw a ray.
- Rotate the protractor to measure 200° (which is 20° beyond a straight line).
- Or: Draw a straight line (180°), then add 20° more in the same direction.
> ⚠️ Tip: For reflex angles like 200°, you may need to extend the protractor’s use or draw the angle going "around" the vertex.
---
- Two angles are congruent if they have the same measure, no matter their orientation or size.
- Example: A 60° angle drawn vertically and another drawn horizontally are congruent.
- They do not need to be in the same location or made with the same lines — just the same degree.
---
- Always label your angles clearly.
- Use a protractor carefully — make sure the center is aligned with the vertex.
- Double-check your measurements.
- For reflex angles (>180°), remember that 200° = 180° + 20°, so draw past a straight line.

If you can describe the angles shown in the image (e.g., "Angle A is a right angle", "Angle B is acute and looks like 45°"), I can give you exact steps for each! Otherwise, follow the method above for any angle.

💡 Key Concept: What Are Congruent Angles?
- Two angles are congruent if they have the same measure, no matter their orientation or size.
- Example: A 60° angle drawn vertically and another drawn horizontally are congruent.
- They do not need to be in the same location or made with the same lines — just the same degree.

✔ Final Tips
- Always label your angles clearly.
- Use a protractor carefully — make sure the center is aligned with the vertex.
- Double-check your measurements.
- For reflex angles (>180°), remember that 200° = 180° + 20°, so draw past a straight line.
