# Geometry Basics: Angle Addition Postulate

## Page 32

---

### Student Information
- **Name:** ___________________________
- **Date:** _______________________
- **Per.:** _______

---

### Instructions
Complete the following exercises using the provided diagram.

---

### Diagram

The diagram features a series of intersecting lines (BF and AC), creating several angles. Points A, B, C, D, E, and F are marked on the lines, dividing them into segments.

*Note: \( \text{BF} \perp \text{AC} \).*

---

### Exercises

1. **Use the diagram to complete each part.**

   a) **Name the vertex of \( \angle 4 \):** ______________
   
   b) **Name the sides of \( \angle 1 \):** ______________
   
   c) **Write another name for \( \angle 5 \):** ______________
   
   d) **Classify each angle:**
   
   \( \angle FBC \): ______________
   
   \( \angle EBF \): ______________
   
   \( \angle ABC \): ______________
   
   e) **Name an angle bisector:** ______________

   f) **If \( m\angle EBD = 36^\circ \) and \( m\angle DBC = 108^\circ \), find \( m\angle EBC \):** ______________

   g) **If \( m\angle EBF = 117^\circ \), find \( m\angle ABE \):** ______________

2. **If \( m\angle MKL = 83^\circ \), \( m\angle JKL = 127^\circ \), and \( m\angle JKM = (9x - 10)^\circ \), find the value of \( x \).**

   *Triangle diagram included with points J, K, L, M.*

   \( x =\) ______________

3. **If \( m\angle EFH = (5x + 1)^\circ \), \( m\angle ZHG = 62^\circ \), and \( m\angle EFG = (18x + 11)^\circ \), find each measure.**

   *Diagram with points E, F, G, H, Z.*

   \( x =\) ______________
