"Understanding Vertical" Intersection and Parallel PPT Courseware 3

First use a protractor to measure the four angles intersecting each set of straight lines to see if they are right angles, and then self-study textbook example 1 and communicate:

(1)What is mutual perpendicularity?

How do you understand the meaning of "mutual"?

(2)What is a vertical line? What is hanging feet?

When two straight lines intersect at right angles, the two straight lines are perpendicular to each other, and one of the straight lines is perpendicular to the other straight line. The intersection of the two straight lines is called the vertical foot.

Line a and line b are perpendicular to each other,

Line a is the perpendicular to line b, or line b is the perpendicular to line a.
