Describe the locus of points at distances greater than or equal to 35 mm from a given point.

Answer

To describe the locus of points that are at distances greater than or equal to 35 mm from a given point, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Point**:
Let’s denote the given point as \( O \). This point is fixed and will serve as the center of our circle.

2. **Determine the Distance**:
We are interested in points that are at a distance greater than or equal to 35 mm from point \( O \).

3. **Draw a Circle**:
To represent the points that are exactly 35 mm away from point \( O \), we will draw a circle with center \( O \) and radius 35 mm.

4. **Understand the Locus**:
- The points that are exactly 35 mm from \( O \) will lie on the circumference of the circle.
- The points that are greater than 35 mm from \( O \) will lie outside this circle.

5. **Describe the Locus**:
Therefore, the locus of points at distances greater than or equal to 35 mm from point \( O \) is:
- The space outside the circle (where the distance is greater than 35 mm).
- The circumference of the circle itself (where the distance is exactly 35 mm).

### Final Answer:
The locus of points at distances greater than or equal to 35 mm from a given point \( O \) is the space outside the circle with radius 35 mm centered at \( O \), including the circumference of the circle.
