How to finding the whole length of a segment given two parts

The video tutorial explains how to find the length of a line segment by adding the lengths of its two parts. The segment is divided into two parts, measuring 1.1 cm and 2.7 cm. The instructor demonstrates the addition process, resulting in a total length of 3.8 cm, emphasizing the importance of including units in the final answer.

What is a segment in geometry?

• A line with no endpoints

• A line with one endpoint

• A line with two endpoints

• A line that extends infinitely

If a segment is divided into two parts measuring 1.1 cm and 2.7 cm, what is the total length of the segment?

• 3.7 cm

• 3.8 cm

• 3.9 cm

• 4.0 cm

What is the first step in finding the total length of a segment with given parts?

• Subtract the lengths of the parts

• Add the lengths of the parts

• Multiply the lengths of the parts

• Divide the lengths of the parts

Why is it important to include units in your final answer when calculating length?

• To ensure clarity and accuracy

• To make the answer look longer

• To make the answer more complex

• To confuse the reader

What is the sum of 1.1 and 2.7 when calculated vertically?

• 3.8

• 3.7

• 3.6

• 3.9
