In the figure angle abc=angle adc find 2 triangles in the figure which are similar to each other.

Given that \(\angle ABC = \angle ADC\), we need to find two triangles in the figure that are similar to each other.

### Identifying the Similar Triangles

Since \(\angle ABC = \angle ADC\), we can look for pairs of triangles that share this angle and another angle or side that would make them similar.

### Similar Triangles:
- **\(\triangle ABC\) and \(\triangle ADC\)**

These triangles are similar because:
1. They share the angle \(\angle A\).
2. It is given that \(\angle ABC = \angle ADC\).

So, by the **AA (Angle-Angle) similarity criterion**, \(\triangle ABC \sim \triangle ADC\).

Would you like to explore more on this, such as using these similar triangles to solve for unknown side lengths or other properties?
