90 degrees.
Intersecting lines that form a right angle are perpendicular lines.
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.
perpendicular crosses at a right angle, while intersecting lines don't
the lines are perpendicular, which basically means the two lines intersecting form a right angle
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines, they would form four right angles. Perpendicular lines are written like this: . From its shape, you can already tell that it forms at least two right angles.
Yes, that is the definition of perpendicular.
If it's not 90 degrees, then they're not perpendicular.
Yes.
Yes, that is the definition of perpendicular. 2 lines intersecting to form a right(90o) angle.
Yes. That's one definition of "perpendicular".
yes 90 degrees
Is this a trick question? "Perpendicular" means at right angles = at 90 degrees!
Actually there are 4 angles formed by 2 intersecting lines, and as long as the lines are PERPENDICULAR, the angles are all right angles, 90 degree each.

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.
