Two lines intersecting at a right angle

a. form a line.
b. are parallel.
c. are perpendicular.
d. form a ray.

Two lines intersecting at a right angle C.are perpendicular.

Angles are said to be right-angled if the magnitude of 90°

The line is the link between two points.

There are several positions between the two lines, including:

two lines are parallel lines if the two lines do not meet or do not intersect, and the distance of the two lines is always fixed

Two intersecting lines will have one intersection point

Two lines coincide if they are in one straight line

Two lines that are not parallel will intersect at a point

So the intersecting lines are definitely not parallel, but the lines that are not parallel, the lines that do not necessarily intersect.

Two lines are said to be perpendicular if the vertical line (parallel to the x-axis) and the horizontal line (parallel to the y-axis) intersect to form an angle of 90°

Mathematical symbols symbolized by the perpendicular symbol "⊥"

If we look in the context of a line equation, then the two lines are perpendicular to each other, then the multiplication of the two gradients (slope) will produce a value of -1

the equation of the perpendicular line
