How do you spell parallelogram in English?
What does a parallelogram look like?
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
What is a parallelogram in words?
: a quadrilateral with opposite sides parallel and equal.
What shape is a rhombus?
In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.
Is a rhombus a regular shape?
A rectangle is an irregular polygon because it does not have 4 sides of equal length, though it does have equally sized angles. A rhombus is an irregular polygon because although it does have 4 sides of equal length, it does not have equally sized angles.
Does a rhombus have 4 right angles?
A square has two pairs of parallel sides, four right angles, and all four sides are equal. It is also a rectangle and a parallelogram. A rhombus is defined as a parallelogram with four equal sides. No, because a rhombus does not have to have 4 right angles.
Does a rhombus have a 90 angle?
The intersection of the diagonals of a rhombus form 90 degree (right) angles. This means that they are perpendicular. The diagonals of a rhombus bisect each other.
Is a parallelogram a rhombus?
So opposite sides are congruent and quadrilateral MNOP is a parallelogram. Also, adjacent sides are congruent, so parallelogram MNOP is a rhombus.

Are all angles of rhombus 90?
On the other hand, as the basic property of square states that all its interior angles are right angles, a rhombus is not considered as square, unless all the interior angles measure 90°. Any rhombus includes four angles, out of which the opposite ones are equal to each other.
