Question 1 :
In $\triangle ABC$ and $\triangle DEF$, $\angle B=\angle E,AB=DE,BC=EF$. The two triangles are congruent under ............. axiom.

Question 2 :
<p class="wysiwyg-text-align-left">ABCD is a parallelogram. The sides AB and AD are produced to E&#160;and F respectively, such that AB = BE and AD = DF.</p><p class="wysiwyg-text-align-left">Hence&#160; $\Delta\,BEC\,\cong\,\Delta\,DCF$.</p><p class="wysiwyg-text-align-left"><b>State whether the above statement is true or false.</b></p>

Question 3 :
If hypotenuse and an acute angle of one right triangle are equal to the hypotenuse and an acute angle of another right triangle, then the triangles are congruent.

Question 4 :
If two sides and one angle of a triangle are equal to the two sides and angle of another triangle, then the two triangles are congruent.

Question 5 :
<p class="wysiwyg-text-align-left">&#160;State the congruency of following pairs of triangles.</p><p class="wysiwyg-text-align-left">In $\Delta\,ABC$ and $\Delta PQR $, $BC = QR, $&#160;$\angle\,A\,=\,90^{\circ}, \, \angle \,C \,=\,\angle R = 40^{\circ} $ and $ \angle\, Q \,=\,50^{\circ}$.</p>
