To determine when the tidal bulges of the Moon and Sun are at right angles, we need to understand the relationship between the positions of the Moon, Earth, and Sun during the different phases of the lunar cycle.

1. **Tidal Bulges**: Tidal forces are generated by the gravitational pull of the Moon and the Sun. When they are aligned (i.e., during the new moon and full moon), their combined gravitational forces result in higher high tides and lower low tides, known as "spring tides."

2. **Right Angles**: When the Moon is at a right angle to the Sun - during the first quarter and third quarter phases - the gravitational forces partially cancel each other out. This results in lower high tides and higher low tides, known as "neap tides."

Thus, the tidal bulges of the Moon and Sun are at right angles during:

- **First quarter**
- **Third quarter**

### Final Answer
The tidal bulges of the Moon and Sun are at right angles during the **first quarter** and **third quarter** phases of the lunar cycle.
