Math 6 Chapter 1 Lesson 10: Midpoint of line segment 1. Theory The midpoint of line segment AB is the point M on that line and is equidistant from two points A and B. We have: M is the midpoint of line segment AB \( \Leftrightarrow \left\{ \begin{array}{l}M \in AB\\MA = MB\end{array} \right.\) Or M is midpoint of line segment AB \( \Leftrightarrow … [Read more...] about Math 6 Chapter 1 Lesson 10: Midpoint of line segment

## Math 6 Chapter 1 Lesson 9: Draw a line showing the length

Math 6 Chapter 1 Lesson 9: Draw a line showing the length 1. Summary of theory Tóm 1.1. Draw a line on the ray Example 1: On the Ox ray, draw a line segment OM of length 2cm. Solution guide: How to draw: Known sucker O. We draw the node M as follows: Place the edge of the ruler on the Ox ray so that the zero line of the ruler coincides with the … [Read more...] about Math 6 Chapter 1 Lesson 9: Draw a line showing the length

## Math 6 Chapter 1 Lesson 8: When is AM + MB = AB?

Math 6 Chapter 1 Lesson 8: When is AM + MB = AB? 1. Summary of theory Tóm If point M lies between two points A and B then AM + MB = AB. Conversely, if AM + MB = AB, then point M lies between two points A and B. 2. Illustrated exercise Question 1: Let M points lie between A and B. Know AM = 3cm, AB = 8cm. Calculate MB. Solution guide: Since M lies … [Read more...] about Math 6 Chapter 1 Lesson 8: When is AM + MB = AB?

## Math 6 Chapter 1 Lesson 7: Length of line segment

Math 6 Chapter 1 Lesson 7: Length of line segment 1. Summary of theory Tóm 1.1. Line length Each line segment has a length. The length of the line segment is a number greater than 0. 1.2. Compare two line segments We can compare two line segments by comparing their lengths. Suppose we have: AB = 3cm, CD = 3cm, EG = 4cm I say: Two line … [Read more...] about Math 6 Chapter 1 Lesson 7: Length of line segment
