That IS a parrallelogram!
Parrallelogram
A parralleogram is a quadrilater so a shape with 4 sides that has equal opposites
Vertically opposite angles. (vert. opp.)
It has one pair of opposite angles that are equal but not two.
Yes, opposite angles in a parallelogram must be equal.
a parallelogram has parallel opposite sides and its opposite angles are congruent
Yes, both pairs of opposite angles in a parallelogram are congruent.
Congruent.
They are the pairs of sides which are parallel.
Parrallelogram (it has rotational symmetry but no lines of symmetry)
Consecutive angles of a parallelogram are supplementary.
Consecutive angles in a parallelogram are supplementary.
A parallelogram with 4 right angles is a rectangle.
-- four sides -- four angles -- opposite sides are equal -- opposite sides are parallel -- opposite angles are equal -- adjacent angles are supplementary -- sum of interior angles is 360 degrees -- sum of exterior angles is 360 degrees -- area = (length of the base) x (height) -- can always be formed with two triangles -- diagonals bisect each other
Such a parallelogram is a rectangle.
They can have any name that you want!
