4 Points Angle
This function draws two lines on the image and measures the angle at the intersection of them.
Measurement target
The line passing @
and 2 is drawn.
The angle at the
intersection
of the two lines is
displayed.
Perpendiculars
This function draws a line based on two points specified by the user, then draws a line perpendicular to the reference line
based on a point specified by the user, and measures the length of the perpendicular line.
Measurement target
The line orthogonal to
the reference line is
drawn from 3 and its
length is displayed.
