They have equal opposite internal angles and have adjacent angles as supplementary. Rectangles are special species of the parallelogram. To calculate the sides of a parallelogram, one can apply the Parallelogram Law. Perimeter of a Parallelogram. The opposite internal angles are equal and the adjacent internal angles are supplementary. o b. rectangle c. lozenge d. diamond o o 17. "Difference Between Parallelogram and Rectangle." • Every angle at the vertices is a right angle. … DifferenceBetween.net. (A rectangle has the extra condition that all its angles are equal at 90°, thus all parallelograms are not rectangles.) A parallelogram is inscribed in a rectangle such that its vertices are the midpoints of the sides of the rectangle. Difference Between Rectangle and Parallelogram (With Table). The diagonals of a parallelogram bisect each other. In the case of a parallelogram, the diagonals are unequal, and it bisects the shape into two congruent triangles. Thus all rectangles are parallelograms. https://dl.acm.org/doi/pdf/10.1145/220279.220338, https://www.tandfonline.com/doi/abs/10.1080/14794802.2014.933711, Comparison Table Between Rectangle and Parallelogram, Main Differences Between Rectangle and Parallelogram, Difference Between Pumpkin and Squash (With Table), Difference Between Sneakers and Tennis Shoes (With Table), Difference Between McAfee LiveSafe and Total Protection (With Table), Difference Between HCPCS and CPT (With Table), Difference Between Catholic and Lutheran (With Table), Difference Between Articles of Confederation and Constitution (With Table), Difference Between Verbal and Non-Verbal Communication (With Table), Opposite internal angles are equal and the adjacent angles are supplementary, The diagonals intersect such that the adjacent angles formed are supplementary, The diagonals bisect to form right-angled triangles, The diagonals bisect to form isosceles triangles. 0 0. cool_black_stallion75. There is no need to resubmit your comment. Since the diagonals of a rectangle bisect each other at a right angle, the area formed by the intersection is a right-angled triangle. Construction workers use the fact that the diagonals of a rectangle are congruent (equal) when attempting to build a “square” footing for a building, a patio, a fenced area, a table top, etc. The opposite internal angles of a parallelogram are equal and the adjacent angles are supplementary i.e., the sum of the adjacent angles should be equal to 180 degrees. If specific conditions are applied on a parallelogram, it would form a rectangle. The opposite sides of a rectangle and a parallelogram are parallel to each other. Area of a Parallelogram : The Area is the base times the height: Area = b × h (h is at right angles to b) Example: A parallelogram has a base of 6 m and is 3 m high, what is its Area? A rectangle is a quadrilateral. Notify me of followup comments via e-mail, Written by : Mardi Stratuss. A diagonal of a rectangle divides it into two congruent right triangles. A parallelogram with all 4 interior angles congruent to each other is called a rectangle. This refers to all four-sided geometrical shapes, which are further divided into four categories, namely trapezoids, isosceles trapezoids, kites, and parallelograms. As the name suggests, a parallelogram is a quadrilateral formed by two pairs of parallel lines. Parallelograms are the quadrilaterals with opposite sides as equal and parallel. A rectangle is a parallelogram whose sides intersect at 90° angles. A parallelogram is defined as a quadrilateral (4-sided polygon) with both pairs of opposite sides parallel.
