Is perpendicular two lines that cross?
Not only that; to be "perpendicular", they have to cross at an angle of 90 degrees.
How do you know what the vertex of an angle is?
An angle is formed when two lines meet (or cross). The vertex is the point where the lines meet.An angle is formed when two lines meet (or cross).

How can you determine if two lines are perpendicular?
If the angle formed between the intersecting lines are 90o then the two lines are perpendicular. In 2D coordinate geometry, a perpendicular line has a slope equal to the negative reciprocal of the original line.
What are some examples of parallel lines and a pair of perpendicular lines?
Railroad tracks or the number 11 are parallel lines. A cross or a small t are perpendicular lines. Also the two ll's in the middle of parallel are parallel lines.
What makes two lines perpendicular?
Perpendicular lines are any two lines that intersect at a 90 degree angle.
