Opposite sides are congruent Opposite sides are parallel Opposite angles are equal Consecutive angles are supplementary Diagonals bisect each other Diagonals form 2 equal triangles
Yes, each pair of two opposite sides is parallel and equal in length. This is necessary to achieve the symmetry of the angles.
In a parallelogram opposite sides are parallel to each other.
Yes every parallelogram has bisecting diagonals
A parallelogram is a 4 sided quadrilateral and its opposite sides are parallel to each other.
False. Bisecting diagonals is sufficient to guarantee a parallelogram, but the diagonals will only be perpendicular if the sides of the parallelogram are equal.

TRUE.A rectangle is by definition a parallelogram. A parallelogram is a quadrilateral with 2 pairs of parallel lines. A rectangle is a parallelogram with 4 equal angles which are 360o/4 = 90o.The opposite angles of a parallelogram are equal as well. Therefore the following is true.If one angle is equal to 90o then the opposite angle is 90o. That leaves two angles and 180o. Since the two angles left are equal then they are each 180o/2 which is also 90o.
At the very least, define the term, write about different kinds of symmetry, and give examples of each. You might also add how symmetry is used in the real world.
It depends on the type of parallelogram:The classic generic-looking parallelogram, having no right angles, and having adjacent sides of unequal length, has no lines of symmetry (only point symmetry about the point of intersection of the diagonals).Special types of parallelograms are as follows:A square has 4 lines of symmetry: horizontal, vertical, and one containing each diagonal.A non-square rhombus has two lines of symmetry: one containing each diagonal.A non-square rectangle has two lines of symmetry: horizontal and vertical.
Well i cant think of any shape without a line of symmetry that isn't irregular. * * * * * Most shapes do not have any line of symmetry. Your hand, for instance, or each eye. Your face, if viewed at sufficient detail, is asymmetric.
If you mean which triangle has at least two lines of symmetry, I can answer your question: an equilateral triangle has three lines of symmetry-- one passing through the center of each side and through the opposite point, perpendicular to the side.
Parallelogram
No. It is false. If both of those conditions are met, then the quadrilateral is a square.
