1 .- The ray.
The point P divides the line in r two opposite rays. The point P is the origin of the two rays .
2. - the segment.
points A and B determine a portion of the line s called segment.
Answer these questions:
Answer these questions:
| The s is ... | |
| points A and B do ... | |
| Point A is ... |
|
3 .- Sum of segments.
segments can be added. You have to put on a line, one behind the other.
In this case the segment AB + CD = AD
| The segment AD = | |
| The segment AB = | |
| The segment CD = | |
4 .- other segments.
segment If we want to subtract the MN and PQ, so that the will begin at the same point M. QN segment is the difference.
Answer:
| segment QN = | |
| The segment MN = | |
| The MQ = segment | |
To multiply by 3 the segment AB, will take a line and three times that segment.
Answers to these exercises:
| The segment MN = | |
| The segment AB = |
|
segments AB and BC are not on the same line and are called concatenated.
PQ and QR segments are called row because they are in the same line.
Answers to these exercises:
| segments PQ and QR are ... | |
| segments AB and BC are ... | |
| segments BC and AB are ... | |
| QR and PQ segments are ... | |
7. Draw parallel lines.
see two ways to draw parallel lines with a square and a ruler.
In the first case are the lines a, b, c. In the second case m, n and p.
