goals
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, $\angle{ABC}=35^\circ$.
