Can happen if tangent line is perpendicular to normal line.
Perpendicular if they form right angles if not they form vertical opposite equal angles
A right angle.
One, two or four right angles, depending upon whether one or both line segments continue beyond the point of intersection.
A right angled triangle can only have two acute angles.
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
Two curves which intersect at right angles, ( the angle between the two tangents to the curve) curves at the point of intersection are called orthogonal trajectories. The product of the slopes of the two tangents is -1.

Perpendicular if they form right angles if not they form vertical opposite equal angles
A right angle.
Origin
The intersection of two perpendicular lines creates four right angles, each measuring 90 degrees. These angles are equal and form a cross shape at the point of intersection. The right angles are characteristic of perpendicular lines, which define a specific relationship between their slopes in a coordinate system.
Two perpendicular lines form right angles at their point of intersection.
