- Opposite angles are two angles that don't share a side. A quadrilateral has two pairs of them. - Adjacent angles are angles that share one side. A quadrilateral has four pairs of them.
No, it doesn't have to be. A quadrilateral can definitely be a parallelogram only if: - Both pairs of opposite sides are parallel. - Both pairs of opposite sides are congruent. - One pair of opposite sides are both congruent and parallel. - Both pairs of opposite angles are congruent. - The diagonals bisect each other.
rhombus
true
One side cannot be congruent: it must be congruent to something!
I suppose a square, since each side would be the same length, and therefore congruent to each of the other sides....
Yes they are. Or they could have three pairs of congruent sides, or they could have one pair of congruent angles and two pairs of sides. As far as a triangle goes, if you have at least three pairs of congruent sides or angles they are congruent. This answer is wrong. The triangles are only similar. For congruent trisngles we have the following theorems = Side - side - side, Side - Angle - side , Angle - angle - side, Right triangle - hypotenuse - side.
Not necessarily.
The question is self-contradictory.
No you could have Square, Rectangle, Rhombus, Parallelogram
It could also be a square or a rhombus.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
