Draw a segment AB 1 dm 2 cm long and divide it with dots into small pieces, 2 cm long each.

Draw a segment AB 1 dm 2 cm long and divide it with dots into small pieces, 2 cm long each. How many points do you need to put? How many segments did you get?

Let’s construct a segment AB with a length of 1 dm 2 cm.Since 1 dm = 10 cm, the length of the segment will be equal to 10 cm + 2 cm = 12 cm.

Divide the segment with dots into segments 2 cm long. You should get 12: 2 = 6 segments. Let’s count the number of segments in the picture. Indeed, 6.

Let’s count how many points were needed to divide the segment AB into 6 equal parts.

5 points, not counting the two ends of the line segment AB.
