In the given figure $AB=AC$ and $\angle A=60°$ then the measurement of $\angle C$ is

In the given figure if $\angle A=\angle B$ then $AC:BC$ is

In $△ABC$ if $AB=AC$ and $\angle B=50°$ then find the measurement of $\angle A$.

In triangle $\mathit{△}ABC$ if $\angle C=\angle A$ and $AB=4 \mathrm{cm},AC=5 \mathrm{cm}$ then $BC$ would be

In the given figure $\angle B=55°$. If $D$ is a midpoint of $BC$ and $AB=AC$. Then the measurement of $\angle BAD$ is -

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 $△ABD\cong △BAC, BD=AC \& \angle ABD=\angle BAC$.
