A quadrilateral can be regular or irregular. Irregular quadrilaterals are: rectangle, trapezoid, parallelogram, kite, and rhombus. Diagonals bisect vertex angles. All sides of a square are the same length (equilateral) and all its angles have the same measure (equiangular). The area of a polygon refers to the space occupied by the flat shape. ... rhombus square. In addition to the generalformulas for parallelograms we have area=½pqandp+q=4a. The diagonals of a rhombus areperpendicular. Also opposite angles Also opposite sides are parallel and of equal length. No, it is not. Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon, 5-sided polygon, and hexagon, 6-sided polygon), and 4-gon (in analogy to k-gons for arbitrary values of k).A quadrilateral with vertices , , and is sometimes denoted as . A rhombus is a special case of a parallelogram, and it is a four-sided quadrilateral. No, because a rhombus does not have to have 4 right angles.

Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. A rhombus is a parallelogram with all sides having the same length and therefore opposite angles are equal. It's a type of quadrilateral that is not a parallelogram. area=ab. For example a square, rhombus and rectangle are also parallelograms. p=q=. Yes No Diagonals bisect each other Diagonals are perpendicular Diagonals are congruent Diagonals bisect opposite angles 22. Kite has two pairs of equal adjacent sides and one pair of opposite angles equal. angles "A" square. Square, Rectangle and Rhombus are also Parallelograms. Why don't libraries smell like bookstores? And just to make things clear, some rhombuses are squares, but not all of them. A square has equal sides (marked "s") and every angle is a right angle (90°). The main difference between the two is that, while a rhombus has two opposite internal angles of equal measure, a square … Using the chart below we can answer such questions as: Oh Yes! (We don't say "Having all 90° angles makes it a rectangle except when all sides are equal then it is a square."). A rhombus is sometimes called a rhomb or a diamond. Square, rectangle, rhombus, parallelogram, kite and trapezium are all quadrilaterals. A quadrilateral is a polygon. Because it has 4 equal sides.

Both a rhombus and a square are parallelograms and quadrilaterals (which means they have four sides with parallel opposite sides). Quadrilateral just means "four sides" It is a parallelogram. But it is never equiangular. The definition I found is consistent for quadrilaterals, i.e., a four sided polygon where all sides and interior angles are equal. A rectangle is a four-sided shape where every angle is a right angle (90°). Of course, we can just call it a "regular quadrilateral." CPCTC (Corresponding Parts of Congruent Triangles are Congruent).
