Triangle how to draw it?

Post by trvsco » Thu Jul 21, 2016 7:50 am

Given a triangle where I know the length of the three sides but I dont know the angles, there is in QCAD a method to draw it?
Thanks in advance,
Andrea

Hi Andrea,

the lengths of the three given sides are equal? If not please give us an example. Thanks.

Draw a line with the given length
draw a circle with radius of the length of the second side
draw a circle with radius of the third side on the other side of the first line
now you can draw the rest without knowing the angles
