An angle which is greater than $180^{\circ}$ but less than $360^{\circ}$ is called a $\ldots \ldots \ldots .$.

If two interior angles on the same side of a transversal intersecting two parallel lines are in the ratio $2:3,$ then the greater of the two angles is (in $^{\circ}$)

$\angle P$ and $\angle Q$ are supplementary angles. If $\angle P = \angle Q + 35^{\circ}$,then find $\angle P$ and $\angle Q$.

Prove that the sum of the three angles of a triangle is $180^{\circ}$.

The angles of a triangle are in the ratio $2: 3: 4$. Find the angles of the triangle.

Can a triangle have two obtuse angles? Give reason for your answer.
