### Educational Website: Geometry Problem Explanation

#### Problem Statement
Given triangles \( \triangle ADC \) and \( \triangle AEB \), find the length of segment \( AE \).

#### Diagram Description
The provided diagram shows two right triangles, \( \triangle ADC \) and \( \triangle AEB \), arranged such that:

- \( \triangle ADC \) is a larger right triangle with \( \angle D \) as the right angle.
- \( \triangle AEB \) is a smaller right triangle within \( \triangle ADC \) with \( \angle B \) as the right angle.
  
In the diagram:
- Point \( A \) is the common vertex of both triangles.
- Line segment \( AE \) is shared between the two triangles.
  
Dimensions provided:
- \( DC = 72 \) units
- \( BC = 55 \) units
- \( AB = 88 \) units

### Task
Using the information given in the problem and the diagram, calculate the length of \( AE \).

#### Solution Outline
To find \( AE \), follow these steps:

1. **Identify the Relationships in the Triangles:**
   - Note that \( \triangle AEB \) is similar to \( \triangle ADC \) because they are both right triangles sharing an acute angle at \( A \).

2. **Use the Pythagorean Theorem:**
   - Apply the Pythagorean theorem to both triangles to find the missing side lengths.

3. **Solve for \( AE \):**
   - Utilize the properties of similar triangles to compare side lengths and solve for \( AE \).

Let's walk through these steps in detail to find the length \( AE \).
