Combined with the specific situation, understand "the shortest line segment among all connections between two points"
Know the distance between two points and the distance from a point to a straight line
In the process of solving problems, experience the close connection between mathematics and daily production
Cultivate the ability of observation, phenomenon and hands-on operation
Why build a tunnel?
The shortest line segment between two points
what have you found?
Draw several different line segments from point A outside the straight line to this straight line and measure them.
What can you find?
The vertical line segment is the shortest
A vertical line drawn from a point outside a straight line to the straight line
