Draw two parallel lines running from east to west. Draw a line that crosses these two lines and make it look so good about appears to come from 1 o’clock and goes to 7 o’clock.
Four angles are created each time two lines intersect. Can you see that we could give the four angles the following names?
- northeast
- northwest
- southwest
- southeast
Bristle line created two sets of four angles.
The two Northeast angles are called corresponding angles. Can you see that we have four sets of corresponding angles?
