"Understanding Vertical" Intersection and Parallel PPT Courseware 2

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

How to draw a vertical line?

I just use a protractor to draw an angle of 900.

One of the angles of a triangle ruler is a right angle, so it’s easier to draw with a triangle ruler!

draw a picture

Draw any vertical

1. Use a right-angled side of the triangle ruler to draw a straight line

2. Draw another straight line along the other right-angled side

3. Draw the right angle symbol
