![]() The area of a parallelogram is the region covered by its boundary. The perimeter of a parallelogram is the sum of the length of all its sides and it is calculated with the help of the formula: Perimeter = 2(a + b) where 'a' and 'b' are the two sides of the parallelogram. What is the Perimeter of Parallelogram?Ī parallelogram is a special kind of quadrilateral in which the opposite sides are parallel and equal. For a quadrilateral to be a parallelogram, all the opposite sides must be parallel and equal to each other. For example, a trapezoid is a quadrilateral, but not a parallelogram. ![]() What is the Difference Between a Parallelogram and a Quadrilateral?Īll parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms. A few examples of a parallelogram are rhombus, rectangle, and square. In a parallelogram, the opposite sides are parallel and equal in length. Thus, the perimeter (P) of a parallelogram with sides is, P = 2 (a + b)Ĭheck out the following articles related to parallelograms.įAQs on Parallelogram What is a Parallelogram Shape in Geometry?Ī parallelogram is a quadrilateral which is made up of 2 pairs of parallel sides. The perimeter of a parallelogram is the total length of its boundary and hence it is equal to the sum of all its sides. The area of the parallelogram is calculated with the help of the formula: Area of Parallelogram = Base (b) × Height (h) Perimeter of Parallelogram Observe the following parallelogram which shows the base and the height.Ĭonsider the parallelogram PQRS with base ( b) and height ( h). It can be calculated if we know the length of the base and the height of the parallelogram and it is measured in square units like cm 2, m 2, and inch 2. The area of a parallelogram is the space enclosed between the four sides of a parallelogram. Let us discuss these two formulas of a parallelogram in this section. Here, EG⊥HFĮvery two-dimensional figure has two basic formulas area as well as the perimeter. Diagonals that are perpendicular to each other.Observe the rhombus EFGH to relate it with the following properties. ![]() Here, AC⊥BDĪ rhombus is a parallelogram with four equal sides in which the opposite angles are equal. Observe the square ABCD to relate it with the following properties. Here, AB = DC and AD = BCĪ square is a parallelogram with four equal sides and four right angles. Observe the rectangle ABCD to relate it with the following properties. RectangleĪ rectangle is a parallelogram with two pairs of equal and parallel opposite sides and four right angles. Let us study these parallelograms in detail. It is mainly divided into three special types: Vertices A, Band C are joined to vertices D, E and F respectively (see figure).A parallelogram can be divided into various types depending upon the different properties. In ∆ABC and ∆DEF, AB = DE, AB || DE, BC = EF and BC || EF. ![]() Show that:ĪBCD is a parallelogram and AP and CQ are perpendiculars from vertices A and C on diagonal BD respectively (see figure). In parallelogram ABCD, two points P and Q are taken on diagonal BD such that DP = BQ (see figure). Show that (i) ABCD is a square (ii) diagonal BD bisects ∠B as well as ∠D. ABCD is a rectangle in which diagonal AC bisects ∠A as well as ∠C. Show that diagonal AC bisects ∠A as well as ∠C and diagonal BD bisects ∠B as well as ∠D. Show that if the diagonals of a quadrilateral are equal and bisect each other at right angles, then it is a square.ĭiagonal AC of a parallelogram ABCD bisects ∠A (see figure). Show that the diagonals of a square are equal and bisect each other at right angles. Show that if the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus. Some More Questions From Circles Chapter If the diagonals of a parallelogram are equal, then show that it is a rectangle.
