Math Parallelogram

[pic] A par totallyelogram is a quadrilateral in which pairs of opposite sides atomic number 18 parallel and atomic number 18 congruent. Opposite sides are parallel and qualified in distance, and opposite topples are equal (angles a are the same, and angles b are the same) NOTE: Squares, Rectangles and Rhombuses are all Parallelograms! induce the kind of parallelogram this figure displays? Example 1: [pic] |[pic] |A parallelogram with: | | |all sides equal and | | |angles a and b as right angles | | |Is a square! | Perimeter and bailiwick of a parallelogram Perimeter of a parallelogram: The perimeter can be calculated with the following locution: [pic] Where a and b are the side lengths. Area of a parallelogram The sphere can be calculated with the following formulas: [pic] Where b is the length of the base line, and h is the height of the parallelogram.

[pic] Where a and b are the side lengths and ? is the angle. [pic] Example 2: Find the area and perimeter with the given length and side. |a: |[pic] |Side length a | |b: |[pic] |Side length b | |h: |[pic] |Height | |?: |[pic] |Angle in degrees | The perimeter is calculated: [pic] The area is calculated, using height and b: [pic] The area is calculated, using a, b and angle: [pic] Special parallelograms If all angles are 900 degrees, then(prenominal)ce it is in any case called a rectangle. If all angles are 900 degrees and the lines are of the same length, then it is also called a square. If all sides are of the same length, then it is also called a rhombus. Example 3: The sides of a 900 angle with the... If you want to get a full essay, order it on our website: Orderessay
