Perpendicular lines intersect each other at right angles which is 90 degrees.
Combined angles of 360 degrees around the point of intersection.
It is a perpendicular line that forms a right angle at the point of intersection.
A Vertex is the point of intersection, and a Perpendicular Vertex is a vertex with all 90 degree angles, to be specific.
Intersecting lines.
Perpendicular.
Perpendicular lines intersect each other at right angles which is 90 degrees.
Combined angles of 360 degrees around the point of intersection.
It is a perpendicular line that forms a right angle at the point of intersection.
Perpendicular lines intersect and form a right angle. The lines on a square are perpendicular to each line that it touches.
Can happen if tangent line is perpendicular to normal line.
A Vertex is the point of intersection, and a Perpendicular Vertex is a vertex with all 90 degree angles, to be specific.
An line that is not perpindicular to the other line makes an acute or obtuse angle Oblique lines are not parallel or perpendicular which would be lines that form acute or obtuse angles at the point of intersection.
One, two or four right angles, depending upon whether one or both line segments continue beyond the point of intersection.
Intersecting lines.
lines those of which contain points
A right angle.
