**Delving into the Concept of Segment AB**

In the realm of geometry, understanding the relationship between various segments and angles is crucial for solving complex problems accurately. One such concept that arises frequently is the determination of the length of a segment, given certain parameters and conditions. Let’s embark on an exploration of the diagram provided, unraveling the formula for calculating the length of segment AB.

**Deciphering the Diagram**

The diagram presents a right triangle with segment AB serving as the hypotenuse. Additionally, segments BC and AC represent the other two sides of the triangle. Our objective is to unveil the formula that enables us to determine the length of segment AB, given the lengths of segments BC and AC.

**Introducing the Pythagorean Theorem**

In the realm of right triangles, the Pythagorean theorem stands as a cornerstone, providing a fundamental relationship between the lengths of the sides. This theorem asserts that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. Mathematically, it can be expressed as:

$$AB^2 = BC^2 + AC^2$$

where AB represents the length of the hypotenuse, and BC and AC represent the lengths of the other two sides.

**Unveiling the Formula for Segment AB**

To derive the formula for determining the length of segment AB, we start by rearranging the Pythagorean theorem:

$$AB = sqrt{BC^2 + AC^2}$$

This formula reveals that to find the length of the hypotenuse AB, we need to square the lengths of the other two sides (BC and AC), add them together, and then take the square root of the result.

**Applying the Formula to Practical Scenarios**

Equipped with the formula, we can now delve into practical applications:

**Example 1:**

Consider a right triangle with BC = 3 units and AC = 4 units. Employing the formula:

$$AB = sqrt{BC^2 + AC^2}$$

$$AB = sqrt{3^2 + 4^2}$$

$$AB = sqrt{9 + 16}$$

$$AB = sqrt{25}$$

$$AB = 5$$

Therefore, in this scenario, the length of segment AB is 5 units.

**Example 2:**

Given a right triangle where BC = 6 units and AC = 8 units, we can apply the formula:

$$AB = sqrt{BC^2 + AC^2}$$

$$AB = sqrt{6^2 + 8^2}$$

$$AB = sqrt{36 + 64}$$

$$AB = sqrt{100}$$

$$AB = 10$$

Hence, in this case, the length of segment AB is 10 units.
