Exactly 90 degrees, that is the definition of perpendicular.
The only difference between perpendicular lines and intersecting lines is that perpendicular lines create a right angle at the point of intersection.
Intersecting cross each other whereas perpendicular lines cross at right angles.
Lines have no end (stretch on forever) Line segments start and end.
perpendicular crosses at a right angle, while intersecting lines don't
Two perpendicular lines make up a right angle
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
If the angle between the lines is 90 degrees the lines are perpendicular.
A perpendicular bisector goes through the median of the line while a perpendicular line can be anywhere on the line as long as it is at a 90 degree angle.
Intersecting lines can cross at any angle. Perpendicular lines cross or meet at 90 degrees only.
Perpendicular lines are a subset of intersecting lines. The only difference is that perpendicular lines intersect at an angle of 90o, whereas intersecting lines can converge at any angle.
parellel lines mean they are to lines the same
Intersecting lines may or may not be perpendicular. If the angle of intersection between two intersecting lines is 90 degrees, then the two lines are perpendicular. Otherwise, the lines are not perpendicular. For example: A | | | B ----|----- | | Here, the lines A and B are intersecting. The angle between A and B is 90 degrees. Therefore, line A and line B are perpendicular to each other.
