2 straight lines which cross over (intersect) each other
Example: the letter x
a pair of intersecting lines that are perpendicular
Yes, a pair of intersecting lines always forms a pair of vertical angles.
A cross is a pair of intersecting lines.
Some intersecting lines are perpendicular lines.Take any old pair of intersecting lines. If the angles at the intersectionhappen to be 90 degree angles, then the lines are perpendicular lines.
They only cross once because intersecting lines are only supposed to INTERSECT at one point, hence the name intersecting lines
Once.
no but sometimes yes
perpendicular line
2 pairs.
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
the pair of lines bisecting the angles formed by the given lines
vertical angles
