Shape of an aeroplane is _____ to reduce friction from air.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the shape of an aeroplane that helps in reducing friction from the air.

2. **Identifying the Shape**: The shape of an aeroplane is known as the "aerofoil" shape. This design is specifically created to minimize air resistance.

3. **Defining Streamlined Shape**: The term "streamlined" refers to a shape that allows air to flow smoothly around it, thereby reducing turbulence and friction.
