Opposite angles are equivalent when formed by two intersecting lines
yes, intersecting lines form two pairs of congruent angles
No.
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.
perpendicular lines
Their opposite angles are equal
Two lines in two intersecting planes can be parallel, intersecting, or skew.
draw two intersecting lines that are not perpendicular
Intersecting lines are two lines that cross in a coordinate plane. So, yes, intersecting lines cross.
Yes, they can be two existing lines (not intersecting) and it can be parallel.
Either perpendicular lines if the lines create 90o angles or intersecting lines.
Non-perpendicular intersecting lines. There is no special name.
Opposite angles are equivalent when formed by two intersecting lines
They are two dimensional figures, have 3 or more sides, no curved lines, no intersecting lines, and are closed figures. (It's more than two but it still works)
Two intersecting lines form two pairs of equal and opposite angles.
Two or more lines that meet at a point are called intersecting lines.
No, they aren't, because they are intersecting (parallel lines never intersect).
