Perpendicular Line垂直线
Of four angels formed by two intersecting lines, the one that is less than or equal to 90 degrees is called the angle of two lines. This means that angle of two lines will always be acute angle or right angle
If two lines form an angle of 90 degrees, they are perpendicular
Distance from a point to a line is the length of the line segment that passes through this point and is perpendicular to the given line.
