Understanding Q...

If each pair of opposite sides of a quadrilateral are equal and parallel, then it is a ____________.

Two opposite angles of a parallelogram are $${\left( {3x - 2} \right)^ \circ }$$ and $${\left( {50 - x} \right)^ \circ }$$. Find the value of $$x$$

The measure of an angle of a parallelogram is $$70^0$$. Its remaining angles are:

What values of $$a$$ would make the given quadrilateral a parallelogram.

Boundaries of surfaces are:

ABCD is a parallelogram and X is the mid-point of AB. If $$Area(\Box AXCD) = $$ $$24$$  $${cm}^2$$, Find $$Area(\Delta ABC) $$.

In the above figure, it is given that $$BDEF$$ and $$FDCE$$ are parallelograms. Can you say that $$BD = CD$$? Why or why not?

All the angles of a quadrilateral are equal. What special name is given to this quadrilateral?

Opposite angles of a quadrilateral $$ABCD$$ are equal. If $$AB = 4$$ cm, determine $$CD$$.
