Finding the length of a segment given the whole and part - Free Math Help - Online Tutor

The video tutorial explains how to find the length of a line segment when given the total length and a part of it. It introduces points A, B, and C, with known lengths from B to C and the total length from A to C. The tutorial demonstrates how to calculate the missing length AB by subtracting the known part BC from the total length AC. The key concept is understanding how to find a missing part when given a whole and another part.

What are the points labeled in the line segment problem?

• P, Q, and R

• X, Y, and Z

• A, B, and C

• A, B, and D

If the length from B to C is 1.6 meters and the total length is 4 meters, what is the length of AB?

• 1.4 meters

• 2.4 meters

• 3.4 meters

• 4.6 meters

What is the first step in finding the missing length of a line segment?

• Add the known part to the whole

• Multiply the known part by the whole

• Subtract the known part from the whole

• Divide the whole by the known part

What is the total length of the line segment AC?

• 5 meters

• 1.6 meters

• 3.4 meters

• 4 meters

What is the key concept to remember when finding a missing part of a line segment?

• Add the parts to get the whole

• Subtract the part from the whole to get the other part

• Multiply the parts to get the whole

• Divide the whole by the parts
