A line is said to be perpendicular to another line if the two lines intersect at a right
angle. Explicitly, a first ... means line segment AB is perpendicular to line
segment CD. The point B is .......
Perpendicular lines are two or more lines that intersect at a 90-degree angle, like
the two lines drawn on this graph, and the x and y axes that orient them.
Perpendicular lines are ... of that number. Do the lines look perpendicular to you
And one way to verify: because it sometimes looks like two lines will intersect, .....
it does matter, because perpendicular lines have 4 angles that each equal 90 ...
