It looks like you've uploaded an image of a geometry worksheet titled
"Angle and Segment Bisectors". Since I can't view or process images directly, I'll help you solve the problems based on your description or by guiding you through typical problems found on such worksheets.
However, since you mentioned "I uploaded an image," but no image is visible in this chat, I can't see the specific details (like diagrams, numbers, or questions). But I can still help you if you describe the problem or provide the text from the worksheet.
That said, here’s how we can approach
angle and segment bisector problems typically found on such worksheets:

🔹 Common Types of Problems on This Worksheet:
1.
Finding Missing Angles Using Angle Bisectors
- An angle bisector divides an angle into two equal parts.
- Example: If ∠ABC = 60° and BD is the bisector, then ∠ABD = ∠DBC = 30°.
2.
Using the Angle Bisector Theorem
- In triangle ABC, if AD is the angle bisector of ∠A, then:
$$
\frac{AB}{AC} = \frac{BD}{DC}
$$
3.
Finding Lengths Using Segment Bisectors
- A segment bisector cuts a segment into two equal parts.
- Midpoint formula: For segment with endpoints (x₁, y₁) and (x₂, y₂), midpoint is:
$$
\left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)
$$
4.
Coordinate Geometry Problems
- Finding equations of bisectors using coordinates.
- Using distance formulas.
5.
Multiple Choice Questions
- Identifying which ray is the bisector.
- Solving for variables in expressions involving angles.
6.
Proofs or Justifications
- Explaining why a point lies on a bisector.

✔ How to Proceed:
Please describe one or more of the following:
- The exact question(s) from the worksheet.
- Diagram descriptions (e.g., “Triangle ABC with ray BD splitting angle B”).
- Any given values (angles, lengths, variables).
- The answer choices (if multiple choice).
Alternatively, you can copy-paste the text from the image, and I’ll solve it step-by-step.
For now, here’s a sample problem and solution to illustrate:
---
🌟 Sample Problem:
> In triangle ABC, AD is the angle bisector of ∠A. If AB = 8 cm, AC = 12 cm, and BD = 4 cm, find DC.
🔍 Solution:
Use the
Angle Bisector Theorem:
$$
\frac{AB}{AC} = \frac{BD}{DC}
$$
$$
\frac{8}{12} = \frac{4}{DC}
$$
Simplify:
$$
\frac{2}{3} = \frac{4}{DC}
$$
Cross-multiply:
$$
2 \cdot DC = 12 \Rightarrow DC = 6
$$
✔ So, DC = 6 cm.
