What is a trapezium? How is an isosceles trapezium different from a right trapezium?

The angles of a quadrilateral are in the ratio $1:2:3:4$. What type of a quadrilateral is formed?

In the given trapeziums, find the value of $x$ and $y$.

In the given trapezium, find the value of $x$ and $y$.

In a trapezium $\mathrm{MUST}$, $\mathrm{TS}\parallel \mathrm{MU}$. The perimeter of the trapezium is $48 \mathrm{cm}$. If one of the parallel sides is twice the other and the sum of the two non - parallel sides is $21 \mathrm{cm}$, find the two parallel sides.

$\mathrm{STAR}$ is a trapezium in which $\mathrm{ST}\parallel \mathrm{RA}$. If $\angle \mathrm{S}=50°$ and $\angle \mathrm{T}=50°$, find the other two angles.
