Register with BYJU’S to learn more about quadrilaterals and other Maths concepts. Do any angles appear to be supplementary? Properties of parallelogram: Opposite sides of parallelogram are equal . Properties of a square. Yes, opposite sides look parallel (and of course, you know this property if you know the definition of a parallelogram). Both have their opposite sides equal and parallel to each other. A rectangle is a quadrilateral with all right angles. Hence, the sum of the interior angles of a parallelogram is 360 degrees. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Properties of Parallelograms. Opposite sides are parallel to … Obviously not, and that’s not a property. Students can use these formulas and solve problems based on them. Rhomboid: A special case of a parallelogram that has its opposite sides parallel to each other but adjacent sides are of unequal lengths. Rhombus: If all the sides of a parallelogram are congruent or equal to each other, then it is a rhombus. Key Concepts: Terms in this set (19) Rhombus. The opposite sides of parallelogram are also equal in length. Also, the parallel sides are equal in length. The, Important Questions Class 9 Maths Chapter 9 Areas Parallelograms, types of Parallelogram, depending on various factors. Not even close (in the above figure, one is roughly twice as long as the other, which surprises most people) — not a property. The following questions explore the angles of a parallelogram (refer to the figure again). A parallelogram does not have other names. Solution: We know that the diagonals of a parallelogram bisect each other. A three-dimensional shape has its faces in parallelogram shape, is called parallelepiped. Sum of adjacent angles of a parallelogram is equal to 180 degrees. Proof: Since a rectangle is also a parallelogram so, the result is a direct consequence of the above theorem. Required fields are marked *. All sides and angles are congruent. The properties of a parallelogram are listed below. A parallelogram is a quadrilateral with two pairs of parallel sides. area of parallelogram ABCD = area of parallelogram ABML. Please visit www.doucehouse.com to view more videos like this. Theorem: The area of a parallelogram is the product of its base and the corresponding altitude. Below is the formula to find the parallelogram area: In the above figure, ||gramABCD, Area is given by; where a is the slant length of the side of ||gramABCD and b is the base. In the figure above, you can see, ABCD is a parallelogram, where AB || CD and AD || BC. All the properties are the same for rhombus as for parallelogram. The parallelogram has its opposite sides equal in length.
