Say true or false :
Two diameters of a circle will necessarily intersect.

Answer

To determine whether the statement "Two diameters of a circle will necessarily intersect" is true or false, let's analyze the concept of a diameter in a circle step by step.

### Step-by-Step Solution:

1. **Understanding the Circle**:
- A circle is defined as the set of all points that are equidistant from a fixed point called the center.

**Hint**: Remember that the center is the point from which all points on the circle are equidistant.

2. **Defining a Diameter**:
- A diameter of a circle is a straight line segment that passes through the center of the circle and has its endpoints on the circle.

**Hint**: A diameter divides the circle into two equal halves.

3. **Drawing Two Diameters**:
- Let's draw a circle with center O. Now, we can draw one diameter, say AB, which passes through O. Next, we can draw another diameter, say CD, which also passes through O.

**Hint**: When drawing diameters, ensure that both lines pass through the center of the circle.

4. **Analyzing the Intersection**:
- Since both diameters AB and CD pass through the center O, they will intersect at point O.

**Hint**: The intersection point of the two diameters is the center of the circle.

5. **Conclusion**:
- Since every pair of diameters will always pass through the center of the circle, they will always intersect at that center point. Therefore, the statement "Two diameters of a circle will necessarily intersect" is true.

### Final Answer:
**True** - Two diameters of a circle will necessarily intersect.
