**Problem 22**

**Given:** ∠1 ≅ ∠2

**Prove:**
a. ΔJIG ~ ΔJZY
b. \(\frac{JG}{JY} = \frac{GI}{YZ}\)

**Diagram Explanation:**

There is a triangle JZY with the following elements:

- Points: J, I, G, Y, Z
- One smaller triangle (JIG) is inside the larger triangle (JZY).
- A line intersects the base JY at point G, creating a segment JG within the base.
- Angles are indicated inside the triangles, one at point Z and one at point I, both labeled similarly.
  
According to the information, ∠1 and ∠2 are congruent. The congruency of these angles can be used to prove that the triangles ΔJIG and ΔJZY are similar and that the ratio of the segments JG to JY equals the ratio of the segments GI to YZ.
