Lines and Angle...

In the given figure $$AB\parallel  CD$$ and $$EF\parallel  GH$$. If $$\angle AIF={120}^{o}$$, then $$\angle CJG$$ is

Supplementary angle of $$108.5^{\circ}$$ is

The measure of $$\angle ABC$$ is equal to:

Complementary angle of $$72\displaystyle \frac{1}{2}^{\circ}$$ is:

If the line $${l}_{1}$$ is parallel to line $${l}_{2}$$ in the given figure, what is the value of $$y$$?

By observing above figure, comment on nature of straight line AB and CD

The measure of angle $$y$$ in the given figure is ......... .

Choose the pair of complementary angles:

In fig. lines AB and CD intersects each other at O. If $$\displaystyle \angle AOC={ 30 }^{ o }$$, find $$\displaystyle \angle BOD$$.

In the figure if $$BD \parallel EF$$, then $$\angle CEF$$ is
