Question

This what I got so far <AHB = <KHL  because they are right angles <ABH =<KLH  

**Example 2: Proving that Two Triangles are Similar**

In the diagram, △ABH ∼ △KLH. Use properties of similar triangles to explain why these triangles are similar.

**Solution**

You can use the Vertical Angles Theorem to determine ∠AHB ≅ ∠_____. Because they are right angles, ∠ABH ≅ ∠_____. By the __________, you can conclude that △ABH ∼ △KLH.

**Diagram Explanation:**

- The diagram shows two right triangles, △ABH and △KLH. 
- Triangle △ABH has a right angle at B, labeled as ∠ABH. 
- Triangle △KLH has a right angle at K, labeled as ∠KLH. 
- The triangles share a common angle, ∠AHB, which is vertically opposite to ∠KHL. 

The Vertical Angles Theorem can be applied here to show the equality of the respective angles, proving the triangles are similar by AA (Angle-Angle) similarity criterion.
