Construction of triangle with 2 sides and an angle.ggb
1. Draw  a triangle with following measures  - BC =  8 cms, ∡ABC = 40, AB = 6 cms (BC as the base)
1. What kind of triangle is it?
1. What kind of triangle is it - by sides?
2. What kind of triangle is it - by angles?
2. Would it be possible to draw a triangle, if ∡ABC was changed to 110? Why

Will Triangle ABE fulfill the requirements of the construction?
Yes. 
Hence this is NOT a UNIQUE set of requirments. 
This is Angle -side - side (ASS) and not SAS)
