Triangles Test ...

In a triangle $$ PQR,\:QR= PR $$ and $$ \angle P= 36^{0} .$$ Which is the largest side of the triangle?

In a $$\triangle$$ $$PQR, QR = PR$$ and $$\angle\,P\,=\,36^{\circ}.$$ The largest side of the triangle is:

In the same figure, if $$y > x  > z;$$ arrange sides $$AB, BC$$ and $$AC $$ in descending order according their lengths.

By which congruency are the following pair of triangles congruent:

In $$\Delta\,ABC$$ and $$\Delta \,DEF$$, $$\angle\,B = \angle\,E = 90\,^{\circ}, AC = DF$$ and $$BC = EF.$$

In $$\triangle ABC,$$ $$\angle\,B\,=\,30^{\circ}$$ and $$\angle\,C\,=\,70^{\circ}$$. The greatest side of the triangle is:

If $$AB > AC > BC,$$ arrange the angles $$x, y$$ and $$z$$ in decending order of their values.

$$l$$ and $$m$$ are two parallel lines intersected by another pair of parallel lines $$p$$ and $$q$$. Then:

If in two triangles $$PQR$$ and $$DEF$$, $$PR=\,EF$$, $$QR=\,DE$$ and $$PQ=\,FD$$, then  $$\triangle PQR\cong$$ $$\triangle$$ ___.

D is a point on the side BC of a $$\triangle ABC$$ such that AD bisects $$\angle BAC$$. Then

In $$\Delta ABC$$, if $$\angle A = 50^0$$ and $$\angle B = 60^0$$, then the shortest and largest sides of the triangle, respectively are:
