With the construction“ Angle”, the following angles will be designed from the objects :

                       .        1.        Angle 3 point

                               2.        Angle 4 point

With all angle constructions, the desired angle can be chosen in the "Object

properties" window afterwards.

“Object properties” can be called up by pushing the right mouse button

when the cursor becomes an arrow on the corresponding measured value.

There are three kinds of angles available :

                       1.        Included angle

                       2.        Complement angle

                       3.        Supplement angle
