For the given hexagonal find the value of $x$.

 

In an isosceles triangle $ABC, AB=BC$ with base $AC$ and $\angle A=2x+8, \angle B=4x-20$ then, find the value of $x$ and also verify whether this triangle is acute, obtuse or a right angle triangle.

In the given figure $AB\parallel ED, CA\parallel FD \& BC=EF$ and prove that $△ABC\cong △DEF$.

$ABCD$ is a quadrilateral in which $AD=BC$ and $\angle DAB=\angle CBA$. Prove that $△ABD\cong △BAC, BD=AC \& \angle ABD=\angle BAC$.
