Perpendicular lines meet at right angles
They are mutually perpendicular lines.
perpendicular
If they intersect and form right angles, they're perpendicular.
They do not meet at right angles to one another.
Two straight lines that meet at right angles are perpendicular.
Perpendicular lines meet at right angles
They are mutually perpendicular lines.
perpendicular
The opposite angles are simply called opposite angles. They always have the same measure.
If they intersect and form right angles, they're perpendicular.
They do not meet at right angles to one another.
Angles in trigonometry are the same as any other angles. They are a measure of the separation between two lines which meet at a point.
Perpendicular lines meet at right angles
coordinate plane
That would be two perpendicular lines.
That refers to lines that meet at right angles - angles of 90 degrees.
