yes
No. A parallelogram has two pairs of opposite angles that are equal but to be equiangular, all four angles must be the same. That is not necessarily the case in a parallelogram.
No, like a rhombus 2 of the angles are the same (opposite each other) and the other 2 angles are the same (opposite each other).
It is a rhombus or a parallelogram.
If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).

They are the same because these features are the same: Opposite angles are equal Opposite sides are parrallel No right-angles Four sides-Quadrilateral
It is a rhombus or a parallelogram.
If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).
Being a quadrilateral, the sum of all four angles is 360o.Opposite angles of a parallelogram are equal.Adjacent angles of a parallelogram are supplementary, that is add to 180o.Given one angle of a parallelogram, the other 3 angles can be calculated:the opposite angle is the same;the other two angles are the same as each other and are 180o - the_given_angle
First of all, you know the opposite sides of a parallelogram are equal because of the definition of a parallelogram. Therefore, two adjacent angles in the parallelogram are supplementary, because same-side interior angles in two parallels and a transversal are always supplementary. Therefore, opposite angles in a paralellogram are equal, because two angles both supplementary to a third angle are equal to each other.
All angles of a parallelogram are not necessarily congruent. A parallelogram means that the opposite sides run in straight lines that don't intersect. An example is a rectangle or square. Length of sides DO NOT determine if opposite angles are congruent. As long as opposite sides do not intersect each other at any point (if you continue to draw the lines), then the angles diagonal from each other are the same.
A parallelogram is a quadrilateral (four sided shape) which has two pairs of opposite sides that are parallel. In a square, the opposite sides are parallel, thus a square is also a parallelogram In a rectangle, the opposite sides are parallel, thus a rectangle is also a parallelogram. A rectangle is a parallelogram in which [all] the angles are right angles. A square is a rectangle (and thus a parallelogram) in which all the sides are the same length as well as all the angles being right angles.
No.Parallelograms have two pairs of parallel opposite sides; they do not have to be the same length.The opposite angles of a Parallelogram are equal; they do not have to be 90oA square is required to have all sides equal (opposite sites will be parallel) and all angles 90o (opposite angles are the same)Thus all squares are parallelograms, but only some parallelograms are squares.A rhombus is a parallelogram which has all sides the same length.
They are the pairs of sides which are parallel.
