To name the angles based on the provided diagram, let’s proceed step by step by interpreting the shape and identifying each angle from the labeled points:

### Step 1: Analyzing the Diagram
The figure seems to depict a polygon with several vertices, each labeled with lowercase letters corresponding to different angles.

### Step 2: Identifying the Angles
- **Angle \( a \)**: This appears to be an external angle at point \( a \), formed by the intersection of two polygon sides.
- **Angle \( b \)**: At vertex \( b \), this is likely an external angle adjacent to angle \( a \).
- **Angle \( c \)**: Located at the top of the polygon, possibly a larger internal or external angle formed by two connecting sides.
- **Angle \( d \)**: Situated at vertex \( d \), this looks like an internal angle on the right-hand side of the polygon.
- **Angle \( e \)**: At vertex \( e \), adjacent to angle \( d \), it is possibly an external angle or part of a larger adjacent structure.
- **Angle \( f \)**: This is a right angle at vertex \( f \), indicated by the small square symbol, typically representing a 90° angle.
- **Angle \( g \)**: This is likely an acute angle near vertex \( g \), adjacent to the right angle at \( f \).
- **Angle \( h \)**: At vertex \( h \), this angle appears as an internal acute angle, connected to angles \( g \) and \( j \).
- **Angle \( i \)**: Positioned at vertex \( i \), which could be a reflex or external angle between sides \( i \) and \( j \).
- **Angle \( j \)**: Finally, this angle is at the intersection of side \( j \) and vertex \( h \), connected to angles \( i \) and \( a \).

### Step 3: Conclusion
To summarize, the angles at points \( a, b, c, d, e, f, g, h, i, j \) are primarily external and internal angles of a polygon, with \( f \) specifically being a right angle. The angles \( g \) and \( h \) seem to be acute, while \( c \) and \( i \) might be reflex angles.
