Lines and Angle...

In figure, the reflex $$ \angle AOB$$ is equal to :

A pair of corresponding angle is 

In figure, which of the following pairs of angles are corresponding angles:

$$M$$ and $$N$$ are 

$$r$$ and $$s$$ are 

An angle is $$18^{\circ}$$ less than its complementary angle. The measure of this angle is

In the given figure, $$ABC$$ is an isosceles triangle with $$AB=AC$$. If $$AE=AF$$ and $$\angle BAE=40^0$$, then the measure of the angle $$FEC$$ is  

A pair of alternate exterior angles is

Lines AC and BD intersect at point E. Angle BEC is $$45^o$$. What is the measure of angle AEB?

If two straight lines intersect, the measures of the vertically opposite angles are ..........
