### Triangle Angle Analysis

In this interactive learning tool, users can explore the internal angles of a triangle. The diagram provided includes a triangle with the following angle measurements:

- **56° (Bottom left corner)**: One angle of the triangle is marked as 56 degrees.
- **105° (Top angle)**: Another angle of the triangle is marked as 105 degrees.
- **41° (Bottom right corner)**: The third angle of the triangle is marked as 41 degrees.

#### Diagram Explanation
- The triangle is depicted with three distinct internal angles, each marked clearly within the diagram.
- The angle at the bottom left corner includes a perpendicular square symbol, indicating that the angle may be right (90°); however, the label clarifies that the angle is actually 56°.
- The top angle of the triangle is marked as 105°, suggesting it's an obtuse angle since it is greater than 90°.
- The angle at the bottom right corner is 41°, an acute angle since it is less than 90°.
  
**Interactive Features**:
- There are three 'Reveals Left' indicators at the top - represented by three circles. These suggest that the user has three opportunities to reveal additional information about the triangle or different angles within it.
- A 'Reveal Another' button allows the user to uncover hidden elements of the triangle, encouraging interactive learning and self-quizzing.

This tool is ideal for students learning about triangle properties, specifically the sum of internal angles which add up to 180 degrees, and identifying different types of angles (acute, right, obtuse).
