Description
"Comparing the Length of Line Segments" Basic Plane Graphics PPT Courseware 2
Of all the lines connecting two points, the line segment is the shortest.
The length of the line segment between two points is called the distance between the two points.
Activity 1
Given the line segment a, please use a compass and ruler to draw a line segment AC so that AC=a.
1. Use a ruler to draw a ray AB.
2. Use a compass to measure the length of the known line segment a.
3. On ray AB, draw an arc with point A as the center and a as the radius. Intersect ray AB with point C, that is, intercept AC=a.
Then line segment AC is the created line segment.
Tell us what you learned from this class?
1. Basic properties of line segments: The shortest line segment between two points.
2. Distance between two points: the length of the line segment between two points.
3. Two comparison methods of line segments: superposition method and measurement method.
4. The concept and representation method of the midpoint of a line segment.
discuss:
How do you usually compare the heights of two classmates? Can you take inspiration from the height comparison method to compare the length of two line segments?
