Lines and Triangles

Draw $$\bigtriangleup PQR$$ with $$PQ=4\ cm,QR=3.5\ cm$$ and $$PR=4\ cm$$. What type of triangle is this?
The angles of a triangle are in the ratio $$2:3:4$$.Then  the angles are$$40,60,80$$.Is it true?If true enter 1 else 0.
Assume that, $$\Delta RST \sim \Delta XYZ$$. Complete the following statement.
In triangle ABC; AB=AC and D is a point in BC then , BD=AD.
In the given figure, $$\angle{ABC}=35^\circ$$.
