If $$ABCD$$ is a quadrilateral, $$E, F, G$$ snd $$ H$$ are the midpoints of $$AB, BC, CD$$ and $$DA$$ respectively, then $$EFGH$$ is a ____ .

In the figure above ABCD is a parallelogram $$\displaystyle \overline{DE}, \overline{EF}$$ and $$\displaystyle \overline{BG}$$ are the bisectors of $$\displaystyle \angle ADC, \angle DEB$$ and $$\displaystyle \angle ABC$$ respectively. BG and EF intersect at H. If $$\displaystyle \angle DAB=70^{\circ}$$ then find $$\displaystyle \angle BHE$$

If $$ABCD$$ is a parallelogram whose diagonals intersect at $$O$$ and $$\Delta$$BCD is an equilateral triangle having each side of length $$6$$ cm, then the length of diagonal $$AC$$ is ____ .

If the adjacent angles of the parallelogram are $$x +30^\circ$$ and $$2x- { 90 }^{ \circ}$$, then the smaller angle is

Two adjacent angles of a parallelogram are $$2x+ 30^o$$ and $$5x + 30^o$$. Then the value of $$x$$ is ___ .

If $$x$$ & $$y$$ are opposite angles of a parallelogram. If the adjacent angle to these angles is $$75^o$$. What is the measure of these angles?

If the perimeter of a parallelogram is $$50\ cm$$ and one side is $$12\ cm$$. what is the measure of the other side ?
